P1 – Krazy Kinetics

(Kinetic Theory)

Fundamental rules of kinetic theory 1. All matter is composed of tiny particles. 2. These particles are in constant motion. 3. The amount of motion is proportional to temperature. So, a higher temperature means more motion. 4. Solids, liquids and gases differ in the freedom of motion of their particles and the extent to which the particles interact with each other.

Solids Particles are packed together as closely as they can be. Particles are arranged in a regular, repeating pattern. There is some empty space between the particles but not a lot.

Liquids The particles are moving quickly. Particles are NOT arranged in a regular pattern. There are bigger spaces between the particles. Particles slide over each other.

Gases Particles are moving VERY quickly. Particles are NOT arranged in a regular pattern. Spaces between the particles are HUGE compared. Gases have no fixed shape or volume.


Particles have increasing energy – solid à liquid à gas

The particles vibrate around a fixed point.
