Heat Capacity Assignment Help

7.5 Heat Capacity

The quantity of heat required to raise the temperature of the system by one degree.

Specific Heat

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

Molar Specific Heat

The amount of heat required to raise the temperature of 1 mole of a substance by 1 degree is called molar specific heat.

At constant volume qV = DE

Molar sp. heat at constant volume CV =

At constant pressure qp = DH

Molar sp. heat at constant pressure

Cp =

H = E + PV

H = E + RT (for one mole of ideal gas)



CP = CV + R

CP – CV = R
