| matter | anything that has volume and mass |
| volume | the amount of space that something occupies or the amount of space that something contains |
| meniscus | the curve at a liquid's surface by which you measure the volume of the liquid |
| mass | the amount of matter that something is made of |
| gravity | a force of attraction between objects that is due to their masses |
| weight | a measure of the gravitational force exerted on an object, usually by the Earth |
| newton | (N) the SI unit of force |
| physical property | a property of matter that can be observed or measured without changing the identity of the matter |
| density | the amount of matter in a given space; mass per unit volume |
| ductility | the ability of a substance to be drawn or pulled in a wire |
| malleability | the ability of a substance to be pounded into thin sheets |
| solubility | the ability to dissolve in another substance; more specifically, the amount of solute needed to make a saturated solution using a given amount of solvent at a certain temperature |
| chemical property | a property of matter that describes a substance based on its ability to change into a new substance with different properties |
| characteristic property | a property of a substance that is always the same whether the sample observed is large or small |
| physical change | a change that affects one or more physical properties of a substance; many physical changes are easy to undo |
| chemical change | a change that occurs when one or more substances are changed into entirely new substances with different properties; cannot be reversed using physical means |
| viscosity | liquids resistance to flow |
| elements | building blocks of matter |
| atoms | smallest unit of an element |
| mixture | two or more substances 'stirred' together but not chemically combined |
| compounds | composed of two more more elements |
