I2

Problem 1 A monoatomic ideal gas is initially at pressure p, and volume Vi. The gas may be taken to a new state where po = 3p, and V2 = 3V, in two different ways: (i) Isobaric expansion to 3V, followed by a constant volume process. (ii) On a straight line when plotted on a p - V diagram. Do the following: 1) Show the two cases on a p - V diagram. 2) Compare the work done by the gas in the two cases. 3) Compare the heat absorbed in the two cases. 4) Compare the change in entropy in the two cases
