A Carnot engine operates among the Tc, 273.15 K and Th, 298.15 K, using 1.00mol of an ideal monatomic gas. During the isothermal expansion step, the volume changes to 50.0L. The initial pressure-volume conditions are 1.000 bar and 24.8L. Determine q, w, and delta U for each step of the cycle and for the overall process.
