Problem

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 and

C_p - C_v = b

for nitrogen gas. What is the correct relation between

a

and

b

? (1)

a = 14b

(2)

a = 28b

(3)

a = \frac{1}{14}b

(4)

a = b
