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

`-900J`

B

`-900J`

C

`270J`

D

`900kJ`

Text Solution

Verified by Experts

The correct Answer is:
A
Work done due to change in volume against constant pressure,
`W=-p(V_(2)-V_(1))`
`=-1xx10^(5)Nm^(-2)(1xx10^(-2)-1xx10^(-3))m^(3)`
`=-900Nm=-900J" "(1Nm=1J)`
