Question

. When a solid melts, what happens to the speed and arrangment of the molecules?

Answer 1

Answer:

the molecules of a solid speed up enough that the motion overcomes the attractions so that the molecules can move past each other as a liquid.

Explanation:

its atoms vibrate faster about their fixed points. ... Heat causes the molecules to move faster, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid.
