During each cycle of operation,a refrigerator absorbs 230 J of energy from the freezer and expels 356 J of energy to the room.How much work input is required in each cycle?

Question

Quizplus · Accepted Answer

The work input required for each cycle of a refrigerator can be calculated using the first law of thermodynamics, which states that the energy added to the system (work input) is equal to the increase in internal energy plus the energy expelled to the surroundings. In this case, the refrigerator absorbs 230 J from the freezer and expels 356 J to the room. The difference between these amounts (356 J - 230 J) equals the work input required, which is 126 J.

During Each Cycle of Operation,a Refrigerator Absorbs 230 J of Energy
