A perfect gas at `27^(@)C` is heated at constant pressure so as to double its volume. The temperature of the gas becomes.

A

`54^(@)C`

B

150 K

C

`327^(@)C`

D

300K

Text Solution

Verified by Experts

The correct Answer is:
c
`(V.)/(T.)=(V)/(T) rArr T.=((V.)/(V))T=((2V)/(V))(273+27)=600K rArr T.=327^(@)C`
