Best ResponseYou've already chosen the best response.1this is isothermal process, work done is given by \[ n R T \log \left( V_b \over Va\right)\\ V_a = {10 \text{L}} \\ V_b = {300.4 \over 273.4}*20*22.4 \text{L}\]

Best ResponseYou've already chosen the best response.0Pay attention that in this case n is variable(leaking). so U is not constant(Adiabatic) So you can not find W(work) by int Pdv.
