SPECIFIC HEAT

The amount of heat required to raise the temperature of 1 g of a substance by 1 degree C is called the specific heat of gas.
It is represented by C. Its unit is cal/g degree C or joule/g degree C.

There are two specific heat of gases;

i) Specific heat at constant volume: At constant volume, the amount of heat required to raise the temperature of 1 g of a gas by 1 degree Celsius is called specific heat of constant volume.

ii) Specific heat at constant pressure : At constant pressure, the amount of heat required to raise the temperature of 1 g of a gas by 1 degree Celsius is called specific heat of constant pressure.
