Kinetic-molecular theory explains the behavior of matter as result of the movement of tiny particles named molecules (group of atoms in a defined ratio).

The molecules in a solids (as the ice cubes) are very close to each other and have a very limited movement. The particles vibrate and oscilate but do not translate, their translation speed is zero. The intermolecular forces are high.

When a solid melts (ice cubes transform in liquid water) the molecules start to separate, the intermolecular forces decrease and the molecules gain speed. Yet the intermolecular forces are high enough to keep prevent the independent movement of the molecules (in a gas the intermolecular forces have decreased so much that the gas molecules move independently of each other) 

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.
