ΔΗ 1pts 2.00-mol of a monatomic ideal gas goes from State A to State D via the path A→B-C→D: State A PA-11.0atm, VA-13.00L State B PB 11.0atm, VB-6.50L State C PC-20.0atm, Vc=6.50L State D PD=20.0atm, VD=23.50L Assume that the external pressure is constant during each step and equals the final pressure of the gas for that step. Calculate q for this process. q = 90.05kJ You can use the expressions Cy=3R/2 and Cp=5R/2 to calculate q=nCAT for each step. Note that the Ideal Gas Law enables you to calculate AT (cf AT = A(PV)/(nR)). Do not confuse A(PV) with PAV. Check that you have the correct energy units and be sure you have the sign right (q is defined as the heat ABSORBED BY THE SYSTEM).
