Connecting the statistical and macroscopic approaches to irreversible processes

A cyclic process involving 1 mole of ideal gas is shown in Figure P13.26. (a) Determine the work done on the

gas by the environment during each step (A, B, C, and D) of the cycle. (b) Determine the net work done on the gas WEnv on Gas. (c) Find the work that the gas does on the environment; it is equal to W_{Gas on Env} = -W_{Env on Gas}. (d) Use the ideal gas law to determine the temperature of the gas at each corner of the process (1, 2, 3, and 4). (e) Use the temperatures found in (d) to determine the thermal energy of the gas at each corner of the process and the change in internal thermal energy during each step of the process. (f) Use the results recorded in the previous parts and the first law of thermodynamics to determine the heating during each step of the process. (g) Determine the efficiency of the process.
