A sample of a gas in a cylinder expands 20.51 against 0.6 atm pressure. The work done by the gas is :

A

`12.3 J`

B

`1246 J`

C

`-12.3 J`

D

`-1246 J`

Text Solution

Verified by Experts

The correct Answer is:
D
Work done `W=-P Delta V`
`=-0.6 xx20.5` litre atmosphere
`=-0.6xx20.5xx101.3 J`
`=-1246 J`
