Thermodynamics Question 324

Question: A gas expands adiabatically at constant pressure such that its temperature Ta/V. The value of γ=(Cp/CV) of the gas is

Options:

A) 1.30

B) 1.50

C) 1.67

D) 2.00

Show Answer

Answer:

Correct Answer: B

Solution:

[b] In adiabatic expansion,

pVγ= constant put p=RTV

(RTV)Vγ=constant

TVγ1= constant or TV1γ

T1V

1γ=12

or γ=1+12=32=1.5
