| chemical property | characteristic of a substance that indicates whether it can undergo a chemical change includes acidity, basicity, combustibility and reactivity |
| color | a physical property of matter resulting from light being reflected, or absorbed |
| combustibility | ability of a substance to catch fire and burn easily |
| compound | a substance made of two or more elements that are chemically combined |
| condensation | the change of a substance from a gas to a liquid, which usually takes place when a gas is cooled to or below its boiling point |
| density | mass per unit of volume of a material |
| element | substance in which all the atoms in a sample are alike |
| freezing point | the temperature at which a substance changes from the liquid phase to the solid phase |
| gas | substance that fills space available, no definite volume or shape |
| heat | the movement of thermal energy from one substance to another |
| heat energy | internal motion of particles of matter |
| heat transfer | movement of heat from a warmer object to a colder one |
| vaporization | change from a liquid phase to a gas phase |
| solubility | the amount of a substance that will dissolve in a solute |
| solid | definite shape and definite volume |
| reactivity | ability to combine with another substance |
| physical change | physical change – a change in size, shape, or state of matter |
| phases of matter | the four forms in which matter exists (solid, liquid, gas and plasma) |
| phase change | physical change of matter from one state to a different caused by a change in heat energy (added or removed), there is no change in temperature (example: solid to liquid, liquid to gas or vice versa) |
