| heterogeneous mixture | a mixture in which the diferent parts can be seen and easily separated |
| solute | the part of a solution that is dissolved, such as the sugar in a sugar water solution |
| volume | the amount of space matter occupies; found by formula for regular objects; found by water displacement for irregular objects |
| homogeneous mixture | a mixture that is evenly mixed; the parts cannot be easily seen; cannot be separated by physcial means |
| weight | a measure of the force of gravity on matter; measured with a scale; can vary with the force of gravity |
| density | relates the mass of a material in a given volume; found by formula: D=m/v; physical property of matter that can identify the material |
| solution | an example of a homogeneous mixture; made up of a solvent and a solute |
| mass | the measurement of the amount of matter in an object; measured with a balance; does NOT vary with the force of gravity |
| physical change | any change that alters (changes) the form of matter but does not make any substance in the matter into a different substance (no new matter is formed) |
| solvent | the part of the solution that does the dissolving, such as water in a sugar water solution |
| International System of Units | the system used to measure the properties of matter such as mass, volume, length, and temperature; also called the metric system |
| chemical change | a change in matter that produces one or more new substances; also called a chemical reaction |
