The Kinetic Particle Theory assumes that all matter is made up of tiny, discrete particles that are in constant and random motion.

What is Brownian Motion? What causes Brownian Motion?
Brownian motion refers to the constant, random motion of small suspended particles in a fluid.
Brownian motion is caused by the constant, random bombardment of the fluid particles on the small suspended particles from all directions, causing the small suspended particles to move constantly in a haphazard motion.
Describe in terms of the arrangement and movement of particles, the process of ice melting.
When ice melts, the heat energy gained from surroundings is used to weaken the bonds between particles. The movement of the particles changes from vibrating in fixed positions in the solid state to moving and sliding over one another freely in confined spaces in the liquid state. The arrangement of the particles changes from regularly arranged, tightly packed together in the solid state to irregularly arranged, close together in the liquid state.
The average kinetic energy of the particles remains constant, so temperature remains constant during melting.
