1. Chemistry

2. What is Matter? Matter: anything that has mass and volume
Mass: amount of matter something has
Volume: amount of space something takes up
Name 5 examples of things that have matter.

3. States/Phases of Matter
Particle Model of Matter
Solids, liquids, gases made up of particles too small to see
Solid
has definite shape and volume
particles vibrate and are packed together
Liquid
definite volume but no definite shape
particles move, rotate

4. States/Phases of Matter
Gas
No definite shape or volume
Particles always moving
Particle Model of Matter

5. Physical Properties Phases of Matter Color Solubility Density
Melting Point
Boiling Point

6. Color

7. Solubility ability of something to dissolve
Salt in water vs Rocks in water

8. Density Density = mass/volume Water has a density of 1.
Measure the density of the objects at your lab station.

9. Melting Point
The temperature when something changes state from a solid to a liquid
What is the melting point of water?
32 degrees F, 0 degrees C

10. Boiling Point
The temperature at which liquid boils and changes state to a gas
What is the boiling point of water?
212 degrees F, 100 degrees C

11. Mixtures and Pure Substances
Pure Substance: sample of matter made up of all the same thing
Mixture: system made up of two or more substances that are mixed
How can you tell a mixture from a pure substance?
