# What are the energy formulas involving specific heat mass and temperature change?

E = mass x sp ht x ÃŽÂ”Ã‚Â°t (Finding Energy) where E (Energy) or Q (Quantity of Heat), mass (g), sp ht (aka specific heat, J/gÃ‚Â°C*[typical] or cal/gÃ‚Â°C or kcal/gÃ‚Â°C), and ÃŽÂ”Ã‚Â°t (temperature change). Finding Temperature Change Divide energy by mass multiplied by specific heat. ÃŽ…Â”Ã‚Â°t = Energy -- Mass * sp ht In order to find the final temperature (if problem is asking for this), add or subtract the original temperature and the new temperature together. T f = original temperature +/- new temperature If energy is added, the temperatures will be added together; if energy is removed, the temperatures will be subtracted. Finding Mass Divide energy by specific heat multiplied by temperature change. Mass = Energy ------- sp ht * ÃŽÂ”Ã‚Â°t Finding Specific Heat Divide energy by mass multiplied by temperature change. Sp ht = Energy ------- Mass * ÃŽÂ”Ã‚Â°t Converting Form of Energy (joules, kcal, and cal) Sometimes a problem will have E be shown in cal/gÃ‚Â°C or kcal/gÃ‚Â°C but will be asking for Joules or even vice versa.

# What is the formula to determine the work done in heating or cooling unit volume of a substance?

I understand that the term "work" is used mainly for the transfer of mechanical energy. So, perhaps, the more appropriate term here would be "energy". You would have to find the material's thermal inertia, in this case, its volumetric heat capacity - look it up, usually, or calculate it on the basis… of its specific heat, which you would look up instead. Once you have that, just multiply the volume x the desired difference in temperature. (MORE)

# What is specific heat capacity and what is the formula for specific heat capacity?

Specific heat capacity of a material is the amount of heat in joules required to raise the temperature of one kg of that material through one kelvin. Suppose I would like to know about specific heat capacity of copper material. Now I have 1 g of copper. I raise its temperature right from 20 to 25 de…gree celcius. That is through 5 kelvin. For that, say , I need H joule of heat energy So for 1000 g I have multiply that heat by 1000 and for one kelvin rise I have to divide by 5. So 1000 H / 5 would give the specific heat capacity of copper (MORE)

# What is the formula for calculating volume change due to heat?

That depends on the exact details. For a gas, the ideal gas law is usually a good approximation: other things being equal, the volume is directly proportional to the absolute temperature (that is, the temperature expressed in kelvin). For a liquid or gas, the expansion is much less than in a gas…. You can look up the coefficient of expansion for a specific substance, and then use the definition of the coefficient; that is, the volume change is equal to (volume) times (temperature difference) x (coefficient of volume expansion).
