One mole of a gas occupying `3dm^(3)` expands against a constant external pressure of 1 atm to a volume of 13 lit. The workdone is :-

A

`-10 " atm dm"^3`

B

`-20 " atm dm"^3`

C

`-39 " atm dm"^3`

D

`-48 "atm dm"^3`

Text Solution

Verified by Experts

The correct Answer is:
A
`W_"exp") =- P xx Delta V `
`=-1 xx (13 -3 )=- 10 ` atm `dm^3 `
