1. Study of MATTER, ENERGY, and their INTERACTIONS
Chemistry

2. Matter vs. Energy Matter is anything that takes up space and has mass.
Ex. YOU
Energy is anything that can be used to do work.
Ex. LIGHT
Matter + Energy = Universe

3. Colloids and Suspensions

4. Properties of Matter Physical Property– “what it is”
Chemical Property – “how it behaves”
Length, Mass, Volume
Reactivity
Density
Combustion
Temperature
Explosiveness
Color
Corrosion
Shape
Rusting
Texture
Composition
State

5. Changes in Properties
Physical Changes are changes in a physical property.
Chemical Changes are changes in a chemical property, often resulting in a new substance.
Balling up a piece of paper
Water freezing
Metal rusting
Melting wax
Burning a candle
Baking a cake

6. What’s going on?

7. Matter is made up of… ELEMENTS!
All elements are found on the periodic table.
Elements are represented by Chemical Symbols.
Elements are all found on the Periodic Table
