Particle Theory
What is the Particle Theory of Matter?
All matter is made of tiny moving particles.
Name the three main states of matter.
1. Solid
2. Liquid
3. Gas
When heat is added, particles move this way.
Faster
This state of matter keeps its shape and volume.
Solid
What two things affect how fast particles move.
1. heat
2. pressure
What is condensation?
The process of a gas turning into a liquid.
Particles in a solid are packed this way compared to a liquid or gas.
Tightly
What is boiling?
When a liquid turns into a gas quickly at its boiling point, this process occurs.
Name three key ideas of the Particle Theory.
1. all matter is made of particles
2. particles are always moving
3. particles have spaces between them
What is sublimation?
The process where a solid turns directly into a gas without becoming a liquid first.
