A gas expands from a volume of `1 m^(3)` to a volume of `2m^(3)` against an external pressure of `10^(5) N m^(-2)` . The work done by 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
Work done `(omega) = P Delta V `
= ` P xx (V_(2) - V_(1))`
`=10^(5) xx (2-1) implies 10^(5) J or 10^(2) kJ`
