Four kilomoles of a monatomic ideal gas are at a temperature of 300 K. The gas expands reversibly and isothermally to twice its original volume.
A.) Compute the work done by the gas.
B.) Compute the heat supplied to maintain a constant temperature. (Note that the Gay-Lussac experiment indicates that U=U(T))
