Question: A vertical cylinder fitted with a piston contains 5 kg of R-22 at 10C. Heat is transferred to the system, causing the piston to rise

A vertical cylinder fitted with a piston contains 5 kg of R-22 at 10°C. Heat is transferred to the system, causing the piston to rise until it reaches a set of stops at which point the volume has doubled. Additional heat is transferred until the temperature inside reaches 50°C, at which point the pressure inside the cylinder is 1.3 MPa.
a. What is the quality at the initial state?
b. Calculate the heat transfer for the overall process.
