Specific Heat

The amount of heat required to raise the temperature of 1 g of a substance by 1 degree is called specific heat. Therefore,

Molar heat capacity Description: 45331.png
 
The heat capacity of a system, especially in a gaseous system, determined at constant volume is different from that at constant pressure.
 
At constant volume, qv = ΔE. So, heat capacity at constant volume per mole is given by

At constant pressure, qP = ΔH. So, heat capacity at constant pressure per mole is given by

where CP and CV are molar heat capacities at constant pressure and constant volume, respectively.
