1. The Particle Theory Of Matter

2. Matter Chemistry Anything that has mass and takes up space
The study of matter and the changes it undergoes.
All matter is made of tiny particles
…and there is a theory that summarizes what
scientists have learned about these particles!)

3. The Main Ideas.
All matter is made up of tiny particles that have empty spaces between them.
Different substances are made up of different kinds of particles.
Particles are in constant motion.
The particles of a substance move faster as its temperature increases.
Particles attract each other.

5. Thermal Energy
Thermal Energy: The form of energy transferred during heating and cooling.

6. Adding Heat
When particles are heated up they gain energy and begin to move faster.
When they have enough thermal energy the particles can no longer hold together, this forms the liquid state.
When more heat is added the particles gain so much energy that they fly apart.
The substance is now a gas

7. Pure Substances
A substance that is made up of only one type of particle.
An example of a pure substance is distilled water.

8. Mixtures
A substance that is made up of at least two different types of particles. They can come in all 3 forms: solid liquid and gas.
Examples of mixtures are; apple juice and granola bars.

9. Mechanical Mixtures and Solutions
Mechanical Mixture: you are able to distinguish the substances inside.
Example: granola bar, salad, pizza
Solution: you are NOT able to distinguish the substances inside.
Example: coffee, apple juice
Alloy: When two or more metals are mixed together. This is an example of a solution.
Example: Penny has copper and nickel as well as other types of metals.
