Question | Answer |
anything that has mass and takes up space | matter |
the amount of material that an object has in it | mass |
the amount of space that matter takes up | volume |
ways to describe matter, for example by its color, shape, size, mass, and shape | physical properties |
the three states of matter | solid, liquid, gas |
has a shape and volume of its own | solid |
has a certain volume, but has no shape of its own and takes the shape of its container | liquid |
has no shape or volume of its own | gas |
two or more substances that are mixed together but can be easily separated | mixture |

scientists used agreed on units of measurement so that their measurements will be this | accurate |
unit for measuring length | meter |
100cm= | 1 meter |
1000mm= | 1 meter |
1 kilometer= | 1000 meters |
property of matter, formula is length x width x height | volume |
unit of measuring volume | cubic meter |
volume of a liquid is measured in this unit | liters |
used to measure liquids or irregular solids like small rocks | graduated cylinder |
we use this to measure mass | balance |
basic unit for measuring mass | gram |
how much mass is in a certain volume of matter | density |
a change in matter that changes physical properties, but does not produce a different type of matter | physical change |
the temperature at which matter changes from a solid to a liquid | melting point |
the temperature at which matter changes from a liquid to a gas | boiling point |
the temperature at which matter changes from a liquid to a solid | freezing point |
a change in matter that produces a different kind of matter | chemical change |
3 types of chemical changes | rusting, tarnishing, burning |
