Solve the below problem:
Q: Consider a Carnot-cycle heat pump having 1 kg of nitrogen gas in a cylinder/piston arrangement. This heat pump operates between reservoirs at 300 K and 400 K. At the beginning of the low-temperature heat addition, the pressure is 1 MPa. During this process the volume triples.
Analyze each of the four processes in the cycle and determine
a. The pressure, volume, and temperature at each point
b. The work and heat transfer for each process
