States of Matter are the physical forms in which a substance can exist.
Particle Theory
Liquids
Gas
Matter is made up of tiny particles called atoms and molecules.
Solids
Particles are arranged close together
Have a set volume
Matter is made up of tiny particles called atoms and molecules.
Matter is made up of tiny particles called atoms and molecules.
There are four main ideas in the particle model:
- All matter is made up of tiny particles. particle model
- The particles of matter are always moving.
- The particles have spaces between them.
- Adding heat to matter makes the particles move faster.
Forces of attraction between particles is strong
Have definite volume but no shape
particles flow freely
Particles are spaced further apart and have weaker forces of attraction
take the shape of the container
Low forces of attraction
No fixed volume or shape
high energy causing particles to move freely
