what happens when you heat a solid? heating a substance increases its thermal energy. when the particles in a solid have more thermal energy, they vibrate more quickly, and the temperature of the substance goes up. once the substance reaches a certain temperature, called its melting point, the substance can begin to change state. as more thermal energy is added to the substance, its particles gain enough thermal energy to move around more freely. the particles remain close together, but they are able to slide past one another. when all of the particles have broken out of their fixed positions, the substance has changed state. which of the following happen during this change of state? select all that apply. the substance melts and becomes a liquid. the number of particles in the substance increases. the particles in the substance move far apart.

Answer

Brief Explanations:

When a solid is heated to its melting - point, it changes state to a liquid. During a phase - change like melting, the number of particles remains constant as no new particles are created or destroyed. In the transition from solid to liquid, the particles move more freely but do not move far apart (that happens in the transition from liquid to gas). The correct statement is that the substance melts and becomes a liquid.

Answer:

The substance melts and becomes a liquid.
