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

The net work done on the gas in the cycle ABCDA is :

A

`1076R`

B

`1904R`

C

Zero

D

`276R`

Text Solution

Verified by Experts

The correct Answer is:
D
`W_(ABCDA) = W_(AB) + W_(DC) + W_(CD) + W_(DC)`
=`muR(500-300) + 2.303muR(500)"log"(2)/(2) + muR(300-500) + 2.303muR(300)"log"(1)/(2) = 276R`
Work done on the gas = `-276R`
