Question

define two principal specific heats of a gas . which is greater and why ? find the solution

Answer 1

The two principal specific heats of gas are
1. Specific Heat At Constant Pressure :
The heat required to raise the temperature of the gas by 1 degree when, it is kept at constant pressure is termed as Specific Heat At Constant Pressure..
2. Specific Heat At Constant Volume:
The heat required to raise the temperature of the gas by one degree when, it is kept at constant volume is termed as Specific Heat at constant volume..
specific heat at constant pressure is more than the specific heat at constant volume because the gas can expand in the first case, causing more absorption of heat as compared to other one..
Hope it helps..
