A substance has a melting point of 80 °C. Which of the following is true for the substance? It will also change from a liquid to a gas at 80 °C while the liquid loses energy. It will also change from a liquid to a gas at 80 °C while the liquid gains energy. It will also change from a liquid to a solid at 80 °C while the liquid gains energy. It will also change from a liquid to a solid at 80 °C while the liquid loses energy.

Answer 1

D - It will also change from a liquid to a solid at 80 °C while the liquid loses energy

Step-by-step explanation:

Answer 2

It will also change from a liquid to a solid at 80 °C while the liquid loses energy.

Step-by-step explanation:

Melting point is the temperature at which a substance changes from solid to liquid. This temperature is the same when the substance solidifies, (from liquid to solid state).

To occur phase changes in matter, it is necessary to give or remove heat from a body. Heat is the thermal energy that determines the degree of agitation of molecules. When altered, it can cause changes in the molecular arrangement of substances, causing phase changes.

For solidification to occur (liquid to solid), the substance must lose energy, which causes the molecular vibrations to diminish and become more united.
