The following problems involve one mole of an ideal monatomic gas, CP = 5R/2, in a variable volume piston/cylinder with a stirring paddle, an electric heater, and a cooling coil through which refrigerant can flow (see figure in images). The piston is perfectly insulated. The piston contains 1 g-mole of gas. Unless specified, the initial conditions are: T i = 25oC, P i = 5 bar.   (a) Status: Heater on; cooler off; paddle off; piston fixed. Five kJ are added by the heater. What are the ΔU, ΔS, ΔP, and ΔT? (b) Status: Heater off: cooler off; paddle off; piston moveable. What reversible volume change will give the same temperature rise as in part (a)? Also, what are the ΔU, ΔS, and ΔP? (c) Status: Heater off; cooler off; paddle on; piston fixed. What shaft work will give the same ΔU and ΔS as in part (a)?

Request:

Can you please help me with answering the following question? Do what you can and if you want to show me your work, please organize it well. I asked the same question before, but the person ended up giving me groups of equations that were clustered together without spacing and made no sense when I tried reading them. Thank you for your understanding.
