How does the kinetic particle theory explain melting and boiling?

The kinetic particle theory explains melting and boiling as increases in energy causing particles to move more freely.

The kinetic particle theory is a fundamental concept in physics that describes the behaviour of matter in different states - solid, liquid, and gas. This theory is based on the idea that all matter is composed of tiny particles that are constantly in motion. The energy of these particles, their movement, and the forces between them determine the state of the matter.

In the case of melting, a solid is heated and the particles gain kinetic energy. This energy makes the particles vibrate faster and the bonds between them become weaker. When the energy is sufficient to break these bonds, the solid turns into a liquid. This is the process of melting. The temperature at which this happens is called the melting point. It's important to note that during melting, the temperature remains constant until all the solid has turned into a liquid.

Boiling, on the other hand, occurs when a liquid is heated. The particles gain more kinetic energy and move faster. As the temperature increases, the particles have enough energy to overcome the forces holding them together. They start to move freely and escape from the liquid, turning into a gas. This is the process of boiling. The temperature at which a liquid boils and turns into a gas is called its boiling point. Similar to melting, the temperature remains constant during boiling until all the liquid has turned into a gas.

In summary, the kinetic particle theory explains that as particles gain energy, they move more freely and change from one state to another. This is the basis for understanding melting and boiling.
