Two moles of helium gas are taken over the cycle ABCDA, as shown in the P-T diagram

Assuming the gas to be ideal the work done on the gas in taking it form A to B is :

A

`300R`

B

`400R`

C

`500R`

D

`200R`

Text Solution

Verified by Experts

The correct Answer is:
B
In going from A to B, the process is isobaric.
`:. dW= nRdT= 2R(500-300)= 400R`
