Question a container with a frictionless movable piston, Ask an Expert

Academics

Question: A container with a frictionless, movable piston contains saturated vapor R134a at 100kPa. Heat is added in an isochoric process until the pressure is 140 kPa. Additional heat is added in an isobaric process until the specific volume is 0.20847 m3/kg.

Part A: What is the change in enthalpy for each process and the final temperature?

I need help to determine the change in enthalpy for each process and the final temperature.
