Question

Goal Solve for the performance coefficient of a refrigerator using a five-step process the includes:
1. Making a state table.
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).
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 5.0 moles of helium gas (monatomic). During the process a->b, the volume increases by a factor of 3.0.

Solution-

(1) Fill in the State Table (all pressures in Pascals, all volumes in cubic meters, all temperatures in K).
 Pressure Volume Temperature a b c
(2) Fill in the Process Table (all entries in Joules).
 Work Heat dU a->b b->c c->a
(3) Find the Totals:
 Work = J Heat = J dU = J
(4) Find the heat input (from "cold reservoir") and the heat output (to "hot reservoir"):
 Q-hot = J Q-cold = J
(5) Find the performance coefficient of the refrigerator:
 Coefficient =
