Kinetic Particle Theory

This theory explains the properties of different states of matter and the changes between them. It states that all matter is composed of tiny particles that are in constant, random motion. The more kinetic energy (from heat, for example), the faster the particles move

This theory explains the behavior of particles in different states of matter and the changes between them. It states that all matter is composed of small particles in constant, random motion. The speed and type of this motion depend on the amount of energy the particles have.
Example: In a heated pot of water, the water molecules at the bottom gain kinetic energy, move faster, and escape into the cooler water above, leading to the circulation of heat (convection). The increased motion at a molecular level can eventually lead to the water boiling and turning into a gas, demonstrating a change of state due to increased kinetic energy.
