Work Done In Thermodynamics

The correct answer is C:The expansion of the gas in the refrigerator
This is based on Joule-Thomson effect. Refrigerators cool down their interiors by utilizing the expansion of a gas. The process starts with the compressor, which compresses the refrigerant vapor, raising its pressure, and then directs it into coils located on the refrigerator's exterior. As this hot gas comes into contact with the cooler kitchen air, it undergoes condensation. During this phase, the refrigerant absorbs heat from inside the fridge, effectively lowering the temperature and cooling the air within.
