Two kg of propane are initally saturated liquid at 0C. It undergoes an isentropic process that cools it to -40C.

a) What is the volume after the cooling?

b) If it is subsequently heated at constant volume until its pressure is 4bar, what is its quality after this heating?

c) What temperature and entropy is obtained at this final state?

d) sketch the processes described above on a p-v diagram and a T-s diagram.
