Question

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

(a) a = b

(b) a = 14 b

(c) a = 28b

(d) a = 1b/14

Answer 1

Correct Option (b) a = 14 b

Explanation:

By Mayor's reaction, for 1 g mole of a gas,

C_{p -} C_v = R

So when gram moles are given.

C_{p -} C_v = R/n
