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 =
