One mole of an ideal gas is contained in a cylinder with a movable piston. The temperature is constant at 77°C. Weights are removed suddenly from the piston to give the following sequence of three pressures. (a) P1 = 5.00 atm (initial state) (b) P2 = 2.19 atm (c) P3 = 1.00 atm (final state) What is thet total work (in joules) in going from the initial to the final state by the way of the preceeding two steps? What would be the total work if the process were carried out reversibly? (in J)
