48. (III) A 1.00-mol sample of an ideal monatomic gas, originally at a pressure of 1.00 atm, undergoes a three-step process: (1) it is expanded adiabatically from T sure until its temperature reaches T3; (3) it then returns to its original pressure and temperature by a constant- volume process. (a) Plot these processes on a PV diagram. (b) Determine T3. (c) Calculate the change in internal energy, the work done by the gas, and the heat added to the gas for each process, and (d) for the com- = 550 K to T2 = 389 K; (2) it is compressed at constant pres- plete cycle.
