Question

an ideal gas expands adiabatically so that its temperature varies with volume as t directly proportional to V*-3/4,then the value of Cp/Cv of the gas is
(1)3/5
(2)5/3
(3)7/3
(4)7/4​

Answer 1

Answer:

7/4

Explanation:

V power gamma - 1 =1/T

*T =1/v power gamma - 1

T=1/v power-3/4 - 1

T=1/v power - 7/4

T=v power 7/4
