Use kinetic-molecular theory to describe what happens when an ice cube or icicle melts. include how energy is involved and what happens to the motion of the water molecules

Kinetic-molecular theory explains the behavior of matter in the environment.

The kinetic molecular law states that the molecules are moving at a constant motion.

In the solid, due to closely bonded atoms and the high intermolecular forces, the vibration and oscillation are very less. The ice cube is solid with high intermolecular forces.

On the melting of the ice cube, the water molecules gain energy and intermolecular forces are reduced. The fewer intermolecular forces result in the change in the state of the ice, and the water is formed.

Thus the melting of ice will result in the gain of the energy that results in the increased motion of the water molecules.

i'm assuming that the correct answer is indeed the first one/ "a"..
