Wavailable hint(s) check all that apply. when a solid is converted to a liquid, heat is absorbed. when heat is applied to a solid, the molecular motion decreases as the temperature increases. the average kinetic energy of the system changes while all of a solid is converted to a liquid. the temperature increases while all of a liquid is converted to a gas. temperature remains constant while all of a solid is converted to a liquid.

Here's what I get  

Explanation:

When a solid is converted to a liquid, heat is absorbed. TRUE.

Temperature remains constant while all of a solid is converted to a liquid. TRUE.

When heat is applied to a solid, the molecular motion decreases as the temperature increases. False. Molecular motion increases as the temperature increases.

The average kinetic energy of the system changes while all of a solid is converted to a liquid. False. The temperature remains constant during a phase change, so the average kinetic energy of the system does not change.

The temperature increases while all of a liquid is converted to a gas. False.
