A quantity of propane is contained in a piston-cylinder assembly. this working fluid undergoes a process starting from an initial state of 2.0 mpa and 60oc. at the end of the process the pressure of the propane is 1.0 mpa and the specific entropy is 0.089 kj/kgk higher than at the start of the process.
Determine the temperature of the propane at the end of the process.
