Question:
Helium has (γ=1.67) is initially at a pressure of 18 atm, volume 1 L, and temperature 632 K. It expands isothermally until its volume is 3 L and then it is compressed at a constant pressure until its volume and temperature are such that an adiabatic compression will return the gas to its original state.
A. Sketch this cycle in a pV-diagram.
B. Find the volume and temperature after isobaric compression.
C. the work done during the cycle, and
D. the efficiency of the cycle.
