`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

`249 L`bar

B

`259 L` bar

C

`239 L`bar

D

`220L` bar

Text Solution

Verified by Experts

Initial volume, `V_(1) = 10L`
`V_(2)("final") = (nRT)/(P) = (10 xx 0.083 xx 300)/(1) = 249 L`
`W = P DeltaV =1 xx (249-10) = 239 L` bar
