QUESTION:
An ice-making machine operates in a Carnot cycle. It takes heat from water at 0.0o C and rejects heat to a room at 24.0o C. Suppose that 85.0 kg of water at 0.0o C are converted to ice at 0.0o C. (a) How much heat is discharged into the room? (b) How much energy must be supplied to the device?
ANSWER:Solution 16E Here, we shall have to use the equation of coefficient of performance of a refrigerator, given by QC Q C K = Q HQ C = W …..(1) Here, Q is the heat taken from a colder place, Q is the amount of heat discarded to a C H warmer place and W is the wor
