2. A sample of an ideal gas underwent an expansion against a constant external pressure of 1.0 bar from 1.0 m3, 20.0 bar, and 273 K to 100.0 m3, 1.0 bar, and 273 K. What is the work done by the system on the surroundings
Isn't this impossible? The gas is ideal: PV=nRT, and T is constant so P1V1=P2V2. But that is not satisfied according to the info, so there is no isotherm that can give the work done.
