Problem: Refrigerant 134a is contained within a rigid tank at an initial state of 2.8 bar and 100 C. Heat is removed until the pressure drops to 2.4 bar. During the process a paddle wheel within the tank is turned with a constant torque of 0.6 Nm for 30 revolutions (n=300).

Part A: If the system contains 0.10 kg, compute the required heat transfer.

Please show all work and clearly explain each step.
