Question

which of these indicates that a liquid has transferred thermal energy to the air? the liquid increases in temperature, and its particles lose kinetic energy. the liquid decreases in temperature, and its particles gain kinetic energy. the liquid increases in temperature, and its particles gain kinetic energy. the liquid decreases in temperature, and its particles lose kinetic energy.

Explanation:

When a liquid transfers thermal energy to the air, it loses energy. According to the kinetic - molecular theory, the temperature of a substance is related to the average kinetic energy of its particles. If the liquid loses thermal energy (transfers it to the air), its temperature will decrease. And as the temperature decreases, the average kinetic energy of its particles also decreases (particles lose kinetic energy).

Answer:

The liquid decreases in temperature, and its particles lose kinetic energy.
