Question
1. Calculate the work done on the system when 1.00 mol of gas held behind a piston expands irreversibly from volume of 1.00dm cube to a volume 10.00dm cube against an external pressure of 1.00 bar.
2. A perfect gas expand reversibly at a constant temperature of 298k so that its volume doubles. What is the change in the molar internal energy of the gas?
