Question

Which of these indicates that a liquid has transferred thermal energy to the air?

Answer 1

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

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

Answer 2

When a liquid is transferring thermal energy to  air, there will be a decrease in the temperature of the liquid and its particles also will lose their energy.

EXPLANATION:

Thermal or heat energy transfer takes place through conduction, convection and radiation. In liquids, thermal energy is transferred through convection because liquid particles can move from one place to another.

Convection occurs when particles with increased thermal energy replace particles with less thermal energy. An increase in thermal energy of the liquid will increase kinetic energy of the liquid particles to replace the air particles with lesser thermal energy.
