Q1. An ideal gas undergoes the process a=>b=>c=>a (which is a right triangle with a=>b being the hypotenuse, b=>c being the vertical side, and c=>a being the bottom horizontal side). Pa=Pc=240.0 kPa, Vb=Vc=40.00 L, Va=15.00 L, and Pb= 400.0 kPa. How much work is completed by the system in this process?

Q2. An 82 kg parachutist descends through a vertical height of 350 m with constant speed. Determine the increase in entropy produced by the parachutist; assume the air temperature is 21 degrees C.
