C(p) is always greater than C(V) due to ...

`C_(p)` is always greater than `C_(V)` due to the fact that:-

A

No work is being done on heating the gas at constant volume .

B

When a gas absorbs heat at constant pressure its volume must change so as to do some external work.

C

The internal energy is a functionof temperature only for an ideal gas.

D

For the same rise of temperature ,the internal energy of a gas changes by a smaller amount at constant volume than at constant pressure.

Text Solution

Verified by Experts

The correct Answer is:
A, B
At constant volume, work done by gas it zero.
