Consider the ideal Stirling cycle shown above, working between a
maximum temperature of 600 K and a minimum temperature of 370 K and
a minimum volume of 0.3 L and a maximum volume of 1.6 L. The
working gas of the cycle is 0.10 mol of an ideal gas with
c′v = 20.8 J/mol-K.
Note, +Q = heat absorbed by the gas and +W = work done
by the gas.
