Find the temperature T3 of the gas when it is in state 3. (Keep in mind that this is an ideal gas.)Express T3 in terms of T1.The diagram shows the pressure and volume of an ideal gas during one cycle of an engine. As the gas proceeds from state 1 to state 2, it is heated at constant pressure. It is then cooled at constant volume, until it reaches state 3. The gas is then cooled at constant pressure to state 4. Finally, the gas is heated at constant volume until it returns to state 1.

Work:

W=PV=nRT

A)

The work, W12 = PΔV

W12 = 3P0(4V0 - V0) = 9 P0V0

The diagram shows the pressure and volume of an ideal gas during one cycle of an engine. As the gas proceeds from state 1 to state 2, it is heated at constant pressure. It is then cooled at constant volume, until it reaches state 3. The gas is then cooled at constant pressure to state 4. Finally, the gas is heated at constant volume until it returns to state 1.
