A gas expands adiabatically at constant ...

A gas expands adiabatically at constant pressure such that `T propV^(-1//2)` The value of `gamma (C_(p,m)//C_(v,m))` of the gas will be :

A

1.3

B

1.5

C

1.7

D

2

Text Solution

Verified by Experts

The correct Answer is:
B
`Tprop(1)/(sqrt(V)),TV^(1//2)` = constant
For adiabatic process,
`TV^(gamma-1)`= constant
`therefore" "gamma-1=(1)/(2), gamma=(3)/(2)`
