`10mol` of an ideal gas confined to a volume of `10L` is released into atmosphere at `300K` where the pressure is 1bar. The work done by the gas is `(R = 0.083 L "bar" K^(-1)mol^(-1))`

A

2490L-bar

B

259L-bar

C

239L-bar

D

220L-bar

Text Solution

Verified by Experts

The correct Answer is:
A
Initial volume `=10L`
Final volume `=(nRT)/(P)=(10xx0.83xx300)/(1)=249L`
`DeltaV=249-10=239L`
`W_(pv)=-P_(ext).DeltaV=1xx239=239L`-bar
