Under isothermal conditions, a gas at 300 K expands from 0.1 L to 0.25 L against a constant external pressure of 2 bar. The work done by the gas is [Given that 1 L bar =100 J]

Expansion of a gas against a constant external pressure is an irreversible process. The work done in an irreversible processWork done by the gas is 30 J=PextΔV=PextV2-V1=2(0.25-0.1) =2×0.15 Lbar=0.30×100 J=30 J9100007383
