Density of gas varies with temperature For every five-degree (Celsius) change in temperature, figure about a 0.5-percent change in density. Avgas (aviation gasoline) weighs about 6.02 pounds per US Gallon at 15 degrees C. That increases to 6.40 pounds per US gallon at -40 degrees C. Mogas (automotive gas) is, for the most part, the same. The density of gasoline (C8H18) is 0.694 g / cm^3 at 300 K and 0.622 g / cm^3 at 400 K. Density shouldn't change that much relative to the ground temperature (300 K =80 F).

Why does temperature affect density?

Higher temperature is higher the kinetic energy of molecules. Molecules motion bouncing off each other fighting with inter-molecular force keeping more distance between molecules and atoms, Higher the temperature or energy will then resulted to more volume at the same mass and hence lesser the density.

How does temperature affect density?

ice is less dense than water.. water is more dense (compact molecules) than ice.. when heat is applied to ice, it becomes more dense, as it turns to water.. when cool temperatures are applied to water, the molecules spread out, making it less dense.. when you put ice in a drink, does it sink to the bottom pf the cup, or float? float; because the molecules are less dense.. same with a boat; even though the mass of the actual boat is heavy on LAND, the air inside the boat is less dense than the WATER BELOW, therefore causing it to float. when there is not enough air in the boat, guess what: it sinks.. ok, helium balloons: the mass of the actual balloon has weight. but when it is filled with helium, since air is more dense than helium, it "pushes" the helium balloon UPWARDS. including the small weight of the rubber balloon. when there is no more air (with those escapee balloons) the balloon will pop from pressure and the plain balloon carcass will have no "helium force" pushing it upwards, and will either fall to the ground or get caught on an airplane on the way down.. In general it reduces the density. There are exceptions at various temperature with certain substances, as with the case above with water and ice. However even with these if you add more heat the density will fall.. if a liqude ishot than the atoms move apart witchmakes it less dense

How does temperature affect viscosity and density?

Viscosity: In gasses, forces between atoms are not important and the transfer of momentum (hence force, hence viscosity) between different adjacent regions of a fluid is due to the movement of particles over long distance. Higher temperature means faster movement means higher viscosity in a gas. In liquids, forces between particles dominate and shear force is transmitted through those interactions with adjacent particles. Higher temperature means more short distance particle movement and more varied interaction with neighboring particles thus decreasing the effectiveness of transmitting shear force and decreasing viscosity. (These trends in viscosity are only general and complex interactions of particles can produce different results than described here.) Density: If the pressure is held constant, an increase in temperature normally results in an increase in volume of a liquid, solid or gas. This parallels the explanation of how particle motion at the microscopic level produces pressure by collisions with the walls of the containing volume. More temperature means more energetic particles that have more momentum to transfer to container walls. With constant pressure, the walls expand. (The obvious caveat here is that molecular orientations and molecular forces can be complex and this connection between increased temperature and decrease density is not universally true. The properties of water between 0 Celsius and 4 Celsius are a well known counter example to the general rule.)

Does temperature affect density?

no it does not matter how hot or cold it is ----------- The density is strongly dependent on temperature, especially for gases ! A heated gas has a lower density than a cold gas.

What is the relation between fuel oil density and temperature?

The oil will change densities based on the temperature. When itgets too hot, it will get less dense and visa versa.

How dose temperature affect density?

it does becuz temp it the speed particles are moving so it eects by how spread out the atoms are for the density

How is density affected by temperature?

it is effected by temperature as density is the mass per volume unit of a substance so when the temperature increases or decreases the volume changes as for example if we have a jar of water the water in the jar will become solid if we decrease the temperature and so the volume changes this is how density is affected by temperature

How does temperature affect the density of diesel fuel?

The volume of gasoline expands or contracts 1 percent with each 15-degree temperature change, The Los Angeles Times reported on a State of California-sponsored study that investigated the effect of temperature on retail gasoline.. Density of Diesel increases decreases with increase in temperature.

How does temperature affect the density of liquid?

This is a simple one. . Density is mass divided by volume. . Heat increase causes increase in volume. . Therefore, as mass is constant and volume is increasing, the density will drop. . Hope that helps!

How does temperature affect density of an object?

Density = mass divided by volume. Temp does not effect mass. But most substances increase in volume with increased temp. Thus: higher temp equals lower density.

How do temperature and salinity affect the density of seawater?

As the temperature of a substance decreases, its density increases (because the atoms and molecules become more tightly packed). Therefore, cold water is more dense and sinks below warm water. Saline water is more dense than fresh water because of the densities of the dissolved ions (salts) are greater than water. Therefore, saline water is more dense and sinks below fresh or less saline water.. Warm water is less dense then cold water because the molecules are less tightley packed. However, cold water molecules are very tightley packed makeing the cold water more dense than the warm water.

One of the factors affecting density besides temperature?

Two major factors that determine density (D) are mass (M) andvolume (V). Density is related to those factors by the importantequation D = M/V.

How does density affects temperature?

As temperature rises so does volume.. Density = mass / volume. Hence, for a fixed mass of substance the density will reduce as volume increases. This is because density is inversely proportional to volume.

What affects density more temperature or salinity?

Density is affected by both temperature and salinity. The colderthe temperature and the saltier the substance, the greater thedensity.

How does temperature affect the density of gas?

Density is equal to the mass of the substance divided by the volume of the substance. D=m/V When you heat a gas, it expands. When it expands, its volume increases. If the volume of a substance increases while the mass stays the same (no loss nor gain in mass) then the density will decrease. If the gas cools, the volume will decrease and the density will increase.

Can temperature affect density?

Yes. Density is mass per unit of volume, and as things get warmer, they generally expand and get a bit less dense.. Scroll down to related links and look at "Density of air - Wikipedia". See there: Importance of temperature.

How does the temperature of water affect it's density?

The warmer the water is the less dense it is but the colder it is the more dense it is.. A2:. therefore, warm water rises above cold water

How does air density affects air temperature?

Air density is the same as air pressure.. Pressure is proportional to temperature. If there is more pressure (density) in the air, particles collide together a lot more frequently and increase in temperature.. Therefore, if pressure increases, temperature increases.

How do temperature and salinity each affect density in ocean water?

The temperature control how hot or cold the ocean is. The salinity control how much salt is in the ocean.

Is density affected by temperature?

Temperature often affects the volume of something, and that would affect the density. However, if you put a gas in a sealed container, you could raise the temperature without affecting the density.

How does temperature affects the density of a substancegive examples related to routine usage?

-- Let a glass of water stand around for a while and eventually the water at the top of the glass is warmer than the water at the bottom of the glass. The warmer water is less dense than the colder water, so it floats on top.. -- While you're painting your living room, when you climb the ladder to get at the ceiling, you'll notice immediately that it's pretty warm up there. Since warm air is less dense than cool air, the warm air floats on top, near the ceiling.. -- If you try to boil a pot of water with a blow-torch pointed at the top surface, you'll be there all day and still probably fail. If you want to heat a liquid, you apply the heat to the bottom. As the bottom liquid heats, its density decreases and it rises to the top. At the same time, the cooler, more-dense liquid sinks to the bottom ... where the heat is being applied. The reason we heat liquids from the bottom is that this natural circulation ... caused by changes in density and known as 'convection' ... eventually brings all of the liquid to the place where it can be heated.. -- You have to get up pretty early in the morning if you want to get out for a ride in your hot-air balloon. After you get the balloon unfolded and laid out on the ground, you have to spend hours heating the air in it. The hotter you make the air in the balloon, the less dense it is; eventually you reduce the density far enough that the balloon can float on the density of the surrounding cooler atmosphere.

Why density of a liquid is more affected by changes in temperature than the density of a solid?

liquids are more affected by the surroundings because there is a greater surface area to be affected by outside influences

How does temperatures affect the density of most substances?

if something is more dense it flows the opposite of where the heat is given or the opposite with the coldness

How is volume and density affected when the temperature is decreased?

In general when temperature is decreased the volume decreases and the density increases. This is not true for water around freezingg temperatures, the volume increases and the density decreases and ice floats.

How can a temperature change affect the density of water?

One cubic centimeter of water weighs one gram at 70°F. It is said to have a specific gravity of 1. Water expands when it is heated. It also expands when it freezes. Therefor, when expanded it is less dense than when at room temperature.

How does temperature and pressure affect density?

Pressure and density are directly proportional (all other factors constant) for a gas. If we compress a gas, it gets more dense. high temperature is of lower density, while lower temperature is of higher density

How does temperature affect volume density viscosity and buoyancy?

volume: when you heat it, the particles will spread out, making the substance expand Density: same as above plus the particles are more spread out when heated, making the substance less dense, and when cooled the substance is more dense because the particles are closer together viscosity: same as above

How is the density of a gas affected by temperature and pressure?

The Ideal Gas Law PV=nRT P=pressure V=volume n=moles R=gas constant T=temperature density = grams/volume so Volume=grams/density substituting grams/density for volume into the Ideal Gas Law P(grams/density) =nRT solving for density P(grams)/nRT=density grams/mole is molecular weight M so PM/RT = Density

How does an increase or decrease in temperature affect density?

An increase in temperature usually causes an increase in volume. Since the mass doesn't change, density decreases .

How does alititude affect the temperature and density of air?

Well as you increase in altitude the air thins, because you are getting higher in the Earth's atmosphere which has less density then lower atmospheric levels which makes the air thin.

How does temperature affect the density of a gas?

With cooler temperatures, the gaseous molecules grow closer together and when the temperature is warmer, the gas molecules spread apart(out).

Does the temperature of the water affect the density of the ketchup packet?

This is very unspecific. Density is mass over volume, so I would assume that the temperature of water around it would not effect the mass or volume of the ketchup packet.

Why does temperature affects density?

I don't know but go to and ask on that website, because the only people that can answer things on that website have to be scientists.

How does land temperature affect air density?

If the land is cold and wet it will effect the air density by making the air feel moist.

What is temperature and density?

Temperature is a physical property that gives a quantitative value for how cold or hot something is. Density is a bit easier, just look at its formula D=M/V, it's essentially the amount of stuff taking up a certain area. (the mass per unit of volume.)

How does the density of ice affect the survival of water - dwelling organisms in environments where temperatures fall below the freezing point?

Since ice is less dense then water, the ice will float on top of the water allowing creatures to continue to live under the ice.

How does altitude and temperature affect air pressure and density?

When altitude rises, the air pressure and density both decrease. When temperature rises that means that more air is pushing down on it. So this means that the air pressure and density rise when temperature rises.

Who discovered that temperature is affected by temperature?

Perhaps you mean 'who discovered that thermal properties of materials vary with the temperature at which the measurement is done'. I don't know of a specific answer, but almost anyone who made a thermal measurement could have noticed this.

Is temperature the only thing that affects density?

It is the easiest way to affect the volume which would change the density. However, if you increase the pressure but keep temperature constant the volume will also change. Any change in volume affects density.

How temperature and salinity affect the density of ocean water?

Water is at its maximum density when it is fully saturated at 4 degrees C. less salinity and higher or lower temperatures decrease ocean density.

Do different temperatures affect water density?

Yes. When water freezes, it becomes less dence and floats. When warm, or room temperature, it is liquid and is more dense. This is a rare quality among substances, where most do the opposite and become more dence when they freeze.

How does cold temperature affect density?

there is a property called convection which applies to liquids and gases. that property says colder liquids or gases are denser.

Does temperature variation affect jet fuel volume?

Yes, jet fuel expands when it is hot and contracts when it is cold. It has a coefficient of thermal expansion of about 0.000999/degree C.

Does temperature variation significantly affect volume of jet fuel?

It depends on how significant the temperature variation is. Jet fuel has a coefficient of thermal expansion of 0.00099/C. That means that for every 10 degree Celsius rise in temperature the volume will increase by almost 1%.

Does burning fossil fuel affect climate by raising the earth's average temperature?

Yes it does. Burning fossil fuel (coal, oil and natural gas) releases carbon dioxide, a powerful greenhouse gas. This extra gas in the atmosphere is causing global warming.

How can temperature affect density in a liquid when temperature is decreasing?

Typically, a lower temperature denotes higher density, but many LIQUIDS are uncompressible (water actually expands slightly as it freezes) and therefore density in maintained. FLUIDS on the other hand encompass both liquids and gasses, of which gasses ARE compressible and will increase in density as temperature drops.

How do changes in temperature of air affect its density?

if it is high the density is high so if the temperature is low the density is low.

How water temperature and salinity affect water density and how does this impact a diver?

Density falls as temperature rises, but increases as salinity rises. The only real effect on a diver is that of cold; unless you dive through a halocline (sudden boundary with much more or less salty water), which may affect your buoyancy. I've seen a photograph of a rather impressive halocline in a cave in which incoming fresh water from inland flowed onto sea-water. The diver was standing with his waist just below the boundary, and the optical effect of the halocline made him appear to be standing with his upper body in air. In fact the passage was filled completely with water!

How does temperature affects the density?

Temprature affects the volume, since most objects expand when they are heated. And density is mass / volume.

How does raising the temperature of an object affect its density?

When you raise the temperature the molecules in the object start tomove fast and bounce off one another. They start to move furtherapart. So the density of the object decreases.
