Consider a sample containing 2.00 mol of a monatomic ideal gas that undergoes the following changes from State A to State D:
State A PA=10.5atm, VA=10.00L State B PB=10.5atm, VB=5.00L
State C PC=24.5atm, VC=5.00L
State D PD=24.5atm, VD=22.00L
Assume that the external pressure is constant during each step and equals the final pressure of the gas for that step.
What is the value of q for the overall change from State A (through States B and C) to State D?
What is the value of H for the overall change from State A to State D?
