An ideal gas expands from 10^(-3) m^(3) ...

An ideal gas expands from `10^(-3) m^(3)` to `10^(-2) m^(3)` at 300 K against a constant pressure of `10^(5) Nm^(-2)`. The workdone is

A

`900KJ`

B

`-900J`

C

`270KJ`

D

`-900J`

Text Solution

Verified by Experts

The correct Answer is:
B
Work done during expansion (or by the system)
`=-PxxDeltaV=-1xx10^(5)[10^(-2)-10^(-3)]`
`=-1xx10^(5)xx9xx10^(-3)=-900J`
