An ideal gas expands from `1xx10^(-3)m^(3)` to `1xx10^(-2)m^(3)` at `300K` againts a constant pressure of `1xx10^(5)Nm^(-2)` . The work done is :

A

`900 k J`

B

`-900 k J`

C

`270 k J`

D

`-900 k J`

Text Solution

Verified by Experts

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