Question

which of the following statements about freezing is true? the energy level of the substance decreases. the energy level of the substance increases. the energy level of the substance remains the same. the energy level of the substance makes it disappear.

Explanation:

Freezing is when a liquid loses heat energy (thermal energy is a form of kinetic energy of particles). When heat energy (related to the energy level of the substance) is lost, the kinetic energy of the particles in the liquid decreases. As per the description in the text, when a liquid freezes (becomes a solid), it loses heat energy. So, the energy level of the substance (which is related to the heat energy it has) decreases.

Answer:

The energy level of the substance decreases.
