C p and C v are specific heats at constant pressure and constant volume respectively. It is observed that C p – C v = a for hydrogen gas C p – C v = b for nitrogen gas The correct relation between a and b is-

1. a = b 14 1
2. a = b
3. a = 14 b
4. a = 28 b Students may find similar question in CP exercise sheet : [ JEE Main, Chapter : KTG, Ex.1, Page No.17, Q. No.35 ] [ JEE Advance, Chapter : KTG, Ex.1, Page No.25,Q. No.22 ]
