Please help me with this HW question...

Complete Analysis of a Refrigerator Goal Solve for the performance coefficient of a refrigerator using a five- step process the includes: 1. Making a state table. P 2. Making a process table. 3. Calculating the totals for Work, Heat, and Internal-Energy-Change. 4. Identifying the heat input (cold reservoir) and output (hot reservoir). isothermal 5. Calculating the performance coefficient of the refrigerator. Problem Shown in the figure to the right is a cyclic process undergone by a refrigerator. Your refrigerator shall use 3.0 moles of helium gas b a (monatomic). During the process a->b, the volume increases by a factor of 5.0. V T = 300 K P. = 100,000 Pa Refrigerator Cycle Solution (1) Fill in the State Table (all pressures in Pascals, Pressure Volume Temperature all volumes in cubic meters, all temperatures in K). 100000 300 a 100000 X Work Heat du a- >b K (2) Fill in the Process Table (all entries in Joules). b- >C C- X Work = - X J (3) Find the Totals: Heat = J dU = (4) Find the heat input (from "cold reservoir") and Q-hot = X J the heat output (to "hot reservoir"): Q-cold = X J (5) Find the performance coefficient of the Coefficient = X refrigerator
