An ideal gas expands from 1xx10^(-3)m^(3...

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 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`.
