Problem 3: A thermodynamic cycle is a process that goes through some number of steps and then comes back to where it started. A 4- step cycle is shown at right. At point 4, P = 2 atm, V = 0.5 m, and T = 200 K. A. Describe the type of process for each step (i.e. an isochoric heating, an isobaric contraction, etc.). Explain how you can tell what kind of process it is. If it is not one of the special processes, state so explicitly. a. Step 1 (4 to B): b. Step 2 (B to C): c. Step 3 (C to D): d. Step 4 (D to A): B. Determine the temperature of the gas at each state. a. State B: b. State C c. State D: C. How many particles N are in the gas? P D A C B
