Two moles of an ideal gas are undergone ...

Two moles of an ideal gas are undergone a cyclic process 1-2-3-1. If net heat exchange in the process is 300J, the work done by the gas in the process 2-3 is

A

`-500J`

B

`-5000J`

C

`-3000J`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
D
1-2 `TpropV`
`:.` p=constant
`Q_(n et)=W_(n et)=W_12+W_23+W_31`
`:.` `W_23=Q_(n et)-W_12` (as `W_31=0`)
`=-300-nRDeltaT`
`=-300-2xx8.31xx300`
`-5286J`
