A gas expands from a volume of `1m^(3)` to a volume of `2m^(3)` against an external pressure of `10^(5)Nm^(-2)`. The work done of the gas will be

A

`10^(5) kJ `

B

` 10^(2) kJ`

C

` 10^(2) J`

D

`10^(3)J`

Text Solution

Verified by Experts

The correct Answer is:
b
`w = - PDeltaV = - 10^(5) Nm^(-2) ( 2-1) m^(3) = - 10^(5) Nm = - 10^(5) J = -10^(2) kJ `
