Question
An imaginary ideal gas heat engine operates on the
following cycle:
1. reversible increase in P of gas from P₂ to P, at constant
V2, with temperature change from T₂ to T₁
2. reversible adiabatic expansion from (P₁, V₂, T₁) to
(P2,V1,T3)
3. irreversible decrease in volume of gas at constant
pressure P₂ from V, to V₂, with temperature change from
T3 to T₂
Assuming that one mole of ideal gas is used and C, is
constant,
a) draw the cycle on a PV diagram.
calculate Q and W for each step
