Two moles of helium gas are taken over the cycle ABCDA, as shown in below in P-T diagram. Assuming the gas to be ideal , the work done on the gas in taking it from A to B is

A

300 R

B

400 R

C

500 R

D

200 R

Text Solution

Verified by Experts

The correct Answer is:
B
From A to B in the given figure, the process is isobaric.
`:. W = nRDelta T = 2 xx R xx (500 - 300) = 400 R`
