Part A
Select the correct PV diagram of the following
process: 2.5 L of ideal gas at atmospheric pressure is
cooled at constant pressure to a volume of 1.0 L, and then
expanded isothermally back to 2.5 L, whereupon the pressure is
increased at constant volume until the original pressure is
reached.

In an engine, an almost ideal gas is compressed adiabatically to
half its volume. In doing so, 2570 J of work is done on
the gas.
