A certain refrigerator has a coefficient of performance of 1.8. If this refrigerator absorbs 2.5x10^4 J of heat from the cold reservoir during each cyle, how much mechanical work is needed to run this refrigerator for each cyle? how much heat does the refrigerator dump into the hot reservoir during each cycle?

Question
A certain refrigerator has a coefficient of performance of 1.8. If this refrigerator absorbs 2.5x10^4 J of heat from the cold reservoir during each cyle, how much mechanical work is needed to run this refrigerator for each cyle? how much heat does the refrigerator dump into the hot reservoir during each cycle?
Expert Solution
Step 1
Given data:
A certain refrigerator
Coefficient of performance (COP) = 1.8
Heat absorbed (Qin) = 2.5×104 J
Required:
The mechanical work done and energy dump into hot reservoir during each cycle
