![A1] A thermodynamic cycle of a monatomic ideal gas consists of the following
three stages: (1) a constant volume increase in pressure from (P,,V ) to (P2, Vị); (2) a
constant pressure expansion from (P2, Vi) to (P2, V2); (3) a return to (P1, Vi) following
a straight line on the P" diagram.
a) Show these three stages on a PV diagram.
b) Shade the area on your diagram that corresponds to the net work done
on or by the monatomic ideal gas during a single cycle.
c) Hence or otherwise find an expression for the net work W done by the
monatomic ideal gas during a single cycle.
d) Find the heat Qi absorbed by the gas in stage (1), expressing your
answer in terms of pressures and volumes.
e) Find the heat Q2 absorbed by the gas in stage (2), expressing your
answer in terms of pressures and volumes.
f). If the entropy of the system at (Pi, Vi) is S1, find an expression for S2,
the entropy of the system at (P2, V2), in terms of S,, pressures, volumes, n and R.
