1. Matter

2. Classification of Matter Matter Mixtures Pure Substances Mechanical MixturesElements SolutionsCompounds

3. Pure Substances Only contain one kind of particle Examples: Helium (element) and water (compound) An element is a pure substance that cannot be broken down further by chemical or physical methods. A compound is a pure substance that is made up of 2 or more elements that are chemically combined. Water is an example of a compound because it has hydrogen atoms and oxygen atoms in a ratio of 2:1.

4. Mixtures Some times it is hard to tell the difference between a mixture and a compound. A mixture is when two different things are physically combined and can be separated by physical methods. A mechanical mixture is a mixture where you can see all the different parts ie: pizza, fizzy sprite, textbook. Also called a heterogeneous mixture A solution is a mixture where it all looks the same throughout ie: Kool-Aid, apple juice, salt water. Also called a homogeneous mixture

5. MATTER Anything that has mass and occupies space. PHYSICAL PROPERTIES A characteristic of a substance that you can observe and measure without changing the identity of the substance. Qualitative Physical Properties Observing and describing without a detailed measurement (five senses)

6. 1. COLOUR 2. ODOUR ex. red, colourless, black ex. sweet, spicy, pungent, odourless burnt 3. STATEex. solid, liquid, gas, plasma??? http://www.youtube.com/watch?v=VkeSI_B5Ljc

7. 4. TEXTUREex. fine, coarse, smooth, bumpy 5. LUSTREex. shiny, dull 6. TASTEex. sweet, sour, salty, bitter

8. 7. CLARITYex. clear, cloudy, opaque Transparent- light and objects can be seen clearly through it (ex. window) Transluscent-light travels through but images can’t be seen clearly (ex. frosted window)

9. 8. DUCTILITY - ability to be stretched into thin wires ex. gum

10. 1. HARDNESS - measure of the resistance to scratching Quantitative Physical Properties ex. diamond (very hard) Can be measured and assigned a value. 2. MALLEABILTY - ability to be hammered or shaped by bending, hammering, pressure ex. aluminum http://www.youtube.com/watch?v=nA8y__BMl-o

11. 3.MELTING/ BOILING POINT - fixed temperatures where substances melt or boil ex. water – melt? Boil? 4. SOLUBILITY - the ability of a substance to dissolve in a solvent ex. Koolaid – solvent is water (universal solvent) - solute is Koolaid crystals

12. 5. VISCOSITY - how well a substance flows ex. corn syrup – high viscosity water – lower viscosity 6. DENSITY - the ratio of the mass of a substance to the volume it occupies ex. density of water = 1.0 g/mL http://www.youtube.com/watch?v=7Ft9VDDPWb4
