Question: A vertical cylinder fitted with a piston contains 5 kg of R-22 at 10?C. Heat is transferred causing the piston to rise until 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. Find the work done.

Options

A : 34.1 kJ

B : 44.1 kJ

C : 54.1 kJ

D : 64.1 kJ
