♥ Kinetic Particle Theory
Matter is anything that occupies space and has mass. Matter can exist in 3 physical states : solid, liquid and gaseous, depending on the temperature and pressure of their surroundings. Solids, liquids and gases have different properties as all matter is made up of a large amount of tiny particles which are always in constant random motion.
Using the kinetic particle theory to explain what happens to the particles in a solid when it is heated until it melts
When a solid is heated, the particles absorb heat energy. The particles gain kinetic energy and start to vibrate faster. At a certain temperature known as the melting point, the particles have enough kinetic energy to overcome the strong forces of attraction holding the particles together in the solid. The particles start to break away from one another and the solid becomes a liquid.
