Question
A piston filled with 0.04 mol of an ideal gas expands reversibly from 50.0 mL to 375 mL at a constant temperature of 37.0°C. As it does so, it absorbs 208 J of heat. The values of q and w for the process will be: (R = 8.314 J / mol K) (ln 7.5 = 2.01)

Solution
q = 208 J
U = 0 at constant temperature
U = q + w
w = – q = –208 J
