Question

Work done in a vapor compression
refrigerator is
​

Answer 1

The function of a vapour compression refrigerator is quite simple. Fundamentally, vapor-compression refrigeration consists of a heat engine that runs backwards, so that the heat energy is obtained from a cold reservoir and deposited into a hot reservoir. On the basis of the Second Law of Thermodynamics, the heat energy does not conduct this transfer spontaneously from a cold reservoir to a hot reservoir.

Answer 2

The work done in a vapour compression refrigeration is always negative

Explanation:

• in case of an ideal  compressor in refrigerator there is entry of the people of a gas in the compressor of the refrigerator. Where it is converted into droplets of liquid

•  as a result of this there is formation of of cold Air which circulates inside the refrigerator. in addition to this as there is decrease in the temperature of the refrigerator hence the work done by the refrigerator is always negative. T
