2.25 moles of an ideal gas with CV.m = 3/2R undergoes the transformations described in the following list from an initial state described by T = 310 K and P = 1.00 bar. Calculate q, w, delta U, delta H, and delta S for each process. a. The gas is heated to 675. K at a constant external pressure of 1.00 bar. b. The gas is heated to 675. K at a constant volume corresponding to the initial volume. c. The gas undergoes a reversible isothermal expansion at 310. K until the pressure is one third of its initial value.
