Question

At a given temperature, the specific heat of a gas at constant pressure is always greater than its specific heat at constant volume.

• A. True
• B. False

Answer 1

The correct option is A True

$\text{Explanation:-}$

$C_P>C_V$

This is because at constant pressure when heat is supplied to the gas for increasing temperature , some heat is used up in doing work for increasing volume.

$\text{Hence the correct option is A}$
