5. Matter Pure Substances Mixtures Elements 1 type of atom Compounds 2 or more types of atoms bonded Homogeneous Mixture Heterogeneous Mixture 1 phase 2 or more phases (Solution) Remember: Bonded together Just mixed up Mixed chunks you can see (not uniform) Mixed up completely (uniform) in whole # ratios – cannot be broken down using physical means! uniform and definite composition physical blend of two or more components

8. Properties of Matter Chemical Property – relates to substance’s ability to undergo change that transforms it into a different substance ( change in matter ) Physical Property – characteristic that can be observed without changing the identity of the substance ( no change in matter ) Extensive – depends on the AMOUNT of a substance present (ex. Length, mass, volume, solubility) Intensive – does not depend on the amount of a substance present but on the TYPE of matter (ex. Density, malleability, conductivity, color, melting point, boiling point) Ex: Burn, rust, explode
