# Why is the molar specific heat of a gas at constant pressure larger than the molar specific heat at constant volume?

The value of molar specific heat at constant pressure is greater than the value of molar specific heat at constant pressure as the work done increases at constant pressure.

See the step by step solution

## Step 1: Definition of the molar specific heat

The molar specific heat defines through 1 Kelvin temperature, 1 mole substance heat will raise.

## Step 2: Finding the specific reason

The work done is zero at a constant volume. Due to this reason, absorbing gas increases the internal energy of the gas.

At constant pressure, the absorbed gas raises up internal energy and work done in the gas. Due to this reason, the value of molar specific heat at constant pressure is larger than the value of molar specific gas at constant volume.
