Chapter 12, Problem 49P

** The P-versus-T graph in Figure P12.49 describes a cyclic process comprising four hypothetical parts. (a) What happens to the pressure of the gas in each part? (b) What happens to the temperature of the gas in each part? (c) What happens to the volume of the gas in each part? (d) Explain each part microscopically. (e) Use the information from (a)-(c) to represent the same parts in P-versus-V and V-versus-Tgraphs (Hint: It helps to align the P-versus-V graph beside the P-versus-T graph using the same P values on the ordinate (vertical axis) and to place the V-versus-Tgraph below the P-versus-T graph using the same T values on the abscissa (horizontal axis). This helps keep the same scale for the variables.)
