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

A

249 L bar

B

259 L bar

C

239 L bar

D

220 L bar

Text Solution

Verified by Experts

The correct Answer is:
C
Initial volume `V_(1)=10L`
`V_(2)("final")=(nRT)/(P)=(10xx0.083xx300)/(1)=249L`
`w=PDeltaV=1xx(249-10)`
`=239`L bar
