An ideal gas expands in volume from `1 xx 10^(-3) m^(3)` to `1 xx 10^(-2) m^(3)` at 300 K against a constant pressure of `1 xx 10^(5) Nm^(-2)`. The work done is:

A

`-900 J`

B

`-900 KJ`

C

`270 KJ`

D

`+900 KJ`

Text Solution

Verified by Experts

The correct Answer is:
A
`W= - P DeltaV`
`= -1xx10^(5)(1xx10^(-2)-1xx10^(-3))`
`= -1xx10^(5)xx9xx10^(-3)= -900J`.
