A refrigerator operates under the following 3-step cycle: p (atm) P max 35 1 Isotherm V(cm) 0 200 400 600 The minimum temperature in the cycle is 300.0 Kelvin. The working substance of the fridge is a monoatomic gas. (a) Find Q12, Q23, and Q31, the heats added to the gas for each of the three steps (if heat is released from the gas during a step, then that should be negative). (b) Draw an energy transfer diagram that clearly shows the net energy flow in one cycle (these are the pictures that have "hot" on the top and "cold" on the bottom, with arrows showing energy flow into / out of the system). In your diagram, provide numerical values for QH, Qc, and Win. (c) Find the coefficient of performance of this fridge.
