|
Matter |
has mass and volume. It can be classified as the state its in (solid, liquid, gas) and what it's made of. |
|
|
substance |
elements or compounds and cannot be broken down by physical means |
|
|
mixture |
combination of things that can be broken down by physical means |
|
|
element |
made of only one type of atom |
|
|
compound |
more than one type of atom (elements joined) |
|
|
Heterogeneous and Homogeneous |
two types of mixtures |
|
|
Heterogeneous Mixture |
Different throughout, not evenly mixed. Legos, trail mix, Suspensions (oil, water) |
|
|
homogeneous Mixture |
Same throughout, evenly mixed Sweet tea, kool-aid, Solutions |
|
|
Suspension |
Heterogeneous mixture that will separate over time. Can be filtered Dust in the air |
|
|
solution |
When substance dissolves and forms a homogeneous mixture. Cannot be filtered Sugar dissolved in water |
|
|
Filtration |
separates materials based on the size of the particles (cannot be used on a solution because the particles have dissolved) |
|
|
Distillation |
Separates substances in a solution based on boiling point. |
|
|
solution solute solvent |
Glass of Kool-aid substance whose particles are dissolved in a solution. (Kool-aid mix and sugar) The substance in which the solute dissolves. (water) |
|
|
Temperature (higher temp faster dissolve) Particle size (teaspoon of sugar or sugar cube) Agitation (stirring) |
3 factors that affect dissolving rate |
|
|
Solubility Saturation |
The maximum amount of solute that will dissolve in a solvent. When a solution contains as much solute as the solvent can hold at a given temperature. |
