Study of MATTER, ENERGY, and their INTERACTIONS Chemistry

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

Colloids and Suspensions Hierarchy of Matter Matter Homogeneous Substances Element Compound Mixtures Solutions Heterogeneous Colloids and Suspensions

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

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

What’s going on?

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
