5. A particular gas is enclosed in a cylinder with a moveable piston. It is observed that if the walls are adiabatic, a quasi-static increase in volume results in a decrease in pressure according to the equation PV5/3 = constant (Q= 0) (a) Find the quasi-static work done on the system and the net heat transfer to the system in each of the three processes ADB, ACB and AB as shown in the figure below. (b) Describe qualitatively each of the three processes. A small paddle is installed inside the system and is driven by an external motor. The motor exerts a torque N, driving the paddle at an angular velocity, and the pressure of the gas (at constant volume) is observed to increase at the rate dp 20 dt 3 (c) Show that the energy difference of any two states of equal volumes can be determined by this process. Use this fact to evaluate UC-UA and Up-UB. P (Pascal)- 105 10°/32 C ply constant B 10 V (m³)-> 8x10-3
