Question: 1 / 400

Refrigerant gives up heat when

It condenses

When refrigerant is in the process of condensing, it changes from a gas to a liquid state. This change in state releases heat, making it the correct answer. Option B, evaporating, is incorrect because refrigerant absorbs heat when it changes from a liquid to a gas. Option C, compressing, is incorrect because while refrigerant does give up heat in the process of being compressed, it is not during the change in state. Option D, superheating, is incorrect because this process involves adding heat to refrigerant, not giving it up.
