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

270 kJ

B

`-900` kJ

C

`-900J`

D

900 kJ

Text Solution

Verified by Experts

The correct Answer is:
C
`W= - P Delta V= -1 xx 10^(5) (1 xx 10^(-2) -1 xx 10^(-3))= -1 xx 10^(5) xx 9 xx 10^(-3) = -900J`
