Question

Assertion (A) : The specific heat capacity of a gas at constant pressure is greater
than its specific heat capacity at constant volume.
Reason (R) : At constant pressure, some additional heat is needed for doing work
due to the expansion of the gas.

pls solve this fast . ​

Answer 1

Explanation:

The heat capacity at constant pressure CP is greater than the heat capacity at constant volume CV , because when heat is added at constant pressure, the substance expands and work. QV = CV △T = △U + W = △U because no work is done.
