Yesterday, you separated a mixture of solid substances…. Create a possible procedure to separate two liquids.

Theories vs. Laws % Composition Using Graphs to analyze data

I will differentiate between chemical and physical properties.

 The Study of Matter and how it behaves.

 Anything that has mass and takes up space.

 Solids  Liquids  Gasses  Plasma

The properties of matter Properties are characteristics

 Physical properties are: A characteristic that can be measured or observed without changing what a substance’s composition

 Think, pair, share… What are some physical properties of water?  Odorless  Colorless  Liquid at room temperature  Boils at 100 ˚C  Freezes at 0 ˚C  Density = 1 g/mL

 Shiny (luster)  Reddish brown color  Malleable  Ductile  Conducts electricity  Good conductor of heat

 Chemical property… The ability of a substance to combine with, or change into, other substances, Video

 What are some physical properties of Hydrogen?  What are some chemical properties?

Chemical Properties of Copper

 A change that does not change what a substance is made of Paper Copper

 A process that involves a substance changing into one or more other substances

 Color change  Odor  Heat change  Gas is given off (bubbles)

 What are some physical properties?  Chemical Properties?

Classify each of the following as physical or chemical changes: 1. Copper reacts with Nitric Acid 2. Water boils 3. Aluminum Conducts electricity 4. Methane burns
