Extracted text: 1) 1.75 moles of an ideal gas with Cy,m = 3/2 R undergoes the transformations described in the following list from an initial state described by T = 325.K. and P = 1.30 bar. Calculate q, w, AU, AH, and AS for each process. (a) The gas is heated to 575 K at a constant external pressure of 1.30 bar. (b) The gas is heated to 575 K at a constant volume corresponding to the initial volume. (c) The gas undergoes a reversible isothermal expansion at 325K until the pressure is one fourfth of its initial value.
