Chemistry topic 1- States of matter

Particles in a solid

_______ only vibrate around a fixed position, and have a regular structure (pattern)

Particles in a liquid

_______ have more freedom to move than particles in a solid. They collide often.

Particles in a gas

_______ can move around freely at random, and collide less often than particles in a liquid.

Solid and liquids

________ cannot be compressed

Gases

______ can be compressed

kinetic theory

- All matter is made up of tiny, moving particles

- Different substances have different types of particles (atoms, molecules, ions) which have different sizes

- Heavier particles move more slowly than lighter particles at a given temperature

- Particles move constantly

Melting

solid to a liquid

Evaporation

liquid to a gas

condensation

gas to a liquid

solidification

liquid to a solid

sublimation

a solid immediately becomes a gas, skipping the liquid state

de-sublimation

a gas immediately becoming a solid, skipping the liquid state

Diffusion

_______ is the movement of particles (usually gas) from an area of high concentration to an area of low concentration
