An ideal gas with γ = 1.4 is subjected to the following cyclic process, whose starting point is characterized
by p1 = 245 kPa, V1 = 2.19 L: 1. adiabatically expand until the pressure becomes p2 = 16.8 kPa, at which
point the volume has some value V2; 2. isobarically (=constant pressure) reduce the volume back to V1; 3.
isochorically (=constant volume) increase the pressure back to p1.
(a) What value does V2 have?
(b) Draw a p-V diagram for this cyclic process. Make sure you label all important parts of it.
(c) What is the net work done on the gas for the whole cyclic process?
(Careful! It’s on the gas, not by the gas.)
