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=13.50L State B PB=10.5atm, VB=3.50LState C PC=20.0atm, VC=3.50LState D PD=20.0atm, VD=24.50L
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 w for the overall change from State A (through States B and C) to State D?
