13.1
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.
Part B
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.
