Question

1. A vessel contains 2 mol of argon gas at 25°C and is held at a constant pressure of 1.00 bar.The system is allowed to expand reversibly to 1.5 times

the initial volume while being heated to 178°C. Assume the heat capacity at constant pressure is 20.786 J/K and is constant over the temperature range. Determine the q, w, AU, and AH for the system with this change. (20 points)
