As an ice cube melts on a table top it transforms from a solid bank with a defined shape to a puddle with a much greater ability to flow. Thinking at a molecular level what causes this change to occur be sure to discuss the kinetic energy of particles in your answer.

In a solid state, the molecules have the least amount of energy. They just stick close together and vibrate in place. As the molecules gain more energy, they are able to move around more freely. In the liquid state, the molecules have enough energy to sort of tumble over each other.
