A mass of diatomic gas`(gamma=1.4)` at a pressure of 2 atomphere is compressed adiabitically so that its temperature rises from `27^(@)C` to `927^(@)C`. The pressure of the gas in the final state is

A

8 atm

B

28 atm

C

68.7 atm

D

256 atm

Text Solution

Verified by Experts

The correct Answer is:

D

`PpropT^(gamma//gamma-1)`
`P_2/P_1=(T_2/T_1)^(gamma//gamma-1)`
`P_2=P_1(T_2/T_1)^(gamma//gamma-1)`
