Explain how a refrigerator works to cool down warm objects that would otherwise be room temperature

Answer: evaporation

Explanation:

Refrigerators work by causing the refrigerant circulating inside them to change from a liquid into a gas. This process, called evaporation, cools the surrounding area and produces the desired effect.

In general, refrigerators are cooled through the evaporation of a volatile liquid-that is, they use a liquid that evaporates very easily, and this evaporation creates the cooling effect. They then compress the gas into a liquid again, and the whole process starts over.
