Q4: A thermodynamic reversible processes in a closed system cycle consisting of 4 steps for an ideal gas initially at 326.85 °C and 900 Kpa. In the first step, pressure decreases isothermally to 300 Kpa; in the second step, pressure decreases isochoric to 200 Kpa; while in the third step the volume decreases isobaric; while, in the last step the gas returns adiabatically to its initial state. use CP = (7/2)R and CV = (5/2)R. (a) Sketch the cycle on a PV diagram. (b) Determine both T and P for states 1, 2, 3, and 4. (c) Calculate Q, W, AU, and AH for each step of the cycle. %3D

for an ideal gas initially at 326.85 °C and 900 Kpa. In the first step, pressure decreases
isothermally to 300 Kpa; in the second step, pressure decreases isochoric to 200 Kpa; while
in the third step the volume decreases isobaric; while, in the last step the gas returns
adiabatically to its initial state. use CP = (7/2)R and CV = (5/2)R.
(a) Sketch the cycle on a PV diagram.
(b) Determine both T and P for states 1, 2, 3, and 4.
