Consider the cyclic process ABCA, shown ...

Consider the cyclic process ABCA, shown in figure, performed on a sample of `2.0 mol` of an ideal gas. A total of `1200 J` of heat is withdrawn from the sample in the process. Find the work done by the gas during the part BC.

A

`2580 J`

B

`3625 J`

C

`4520 J`

D

`1550 J`

Text Solution

Verified by Experts

The correct Answer is:
C
`W_(AB) = nRT Delta T = 400R`
`W_(CA) = 0`
For the cyclic process `ABCA`
`W_(AB) +W_(BC) +W_(CA) = Delta Q = -1200J`
`implies W_(BC) = -1200-400R =-1200-3320 = -4520J`
