| amount of matter in an object | mass |
| how much space an object takes up | volume |
| A measurement of how fast particles of an object move | temperature |
| anything that has mass and takes up space | matter |
| true or false? All elements have specific characteristics and react differently with different elements. | true |
| A good conductor of heat and electricity | metal |
| elements that do not conduct heat or electricty | nonmetals |
| elements that act like metals and nonmetals | semimetals |
| the smallest part of an element that still has the properties of that element | atom |
| atoms are made up of three things, what are they? | protons, neutrons, and electrons |
| the idea that everything is made up of atoms | atomic theory |
| _____________________________ can be observed, described, and measured, without changing the material | physical property |

| true or false? Melting point and freezing point are the same temperature | true |
| change in matter where liquid becomes a solid | freezing |
| change in matter where solid becomes a liquid | melting |
| change in matter where gas becomes a liquid | condensation |
| change in matter where liquid becomes a gas | evaporation |
| different materials are placed together but maintain their own properties | mixture |
| you can use ________________________ of a substance to separate it from a mixture | physical properties |
| a mixture that is spread out evenly and will not settle | solution |
| substance that is dissolved | solute |
| substance that is doing the dissolving | solvent |
| what are two ways you can make the solute in a solution dissolve quicker? | stirring and heating |
| describes a substances ability to dissolve | solubility |
| a change in matter that happens that does not create a new substance | physical change |
| is crushing a piece of chalk with a hammer a physical or chemical change? Why? | physical, the substance doesn't change |
| Are melting, freezing, evaporation, and condensation physical or chemical changes? | physical |
| one or more types of matter change into other types of matter | chemical change |
| what are some pieces of evidence of a chemical change? | release of heat and light, change in color, new smell, gas bubbles, or formation of a solid |
| is metal rusting a chemical or physical change? why? | chemical, it creates a new substance |
| what does higher temperature do to a chemical change? | speeds it up |
