# Question: A diatomic ideal gas y 1 40 confined to a cylinder

A diatomic ideal gas (y = 1.40) confined to a cylinder is put through a closed cycle. Initially the gas is at Pi, Vi, and Ti. First, its pressure is tripled under constant volume. It then expands adiabatically to its original pressure and finally is compressed isobarically to its original volume.

(a) Draw a PV diagram of this cycle.

(b) Determine the volume at the end of the adiabatic expansion. Find

(c) The temperature of the gas at the start of the adiabatic expansion and

(d) The temperature at the end of the cycle.

(e) What was the net work done on the gas for this cycle?
