Refrigerant 134 a experiences a process for which the pressure-volume relation is p v^ pi= constant. The initial and final states of the refrigerant are fixed by p_1=200 mathrmkPa, T_1=-10^ circ mathrmC and p_2=1000 mathrmkPa, T_2=50^ circ mathrmC, respectively. Estimate the work and heat transfer for the process, each in mathrmkJ per mathrmkg of refrigerant.
