Unit 1 Matter
| Term | Definition |
|---|---|
| Matter | anything that has mass and takes up space |
| Mass | describes the amount of matter in an object |
| Weight | a measure of the gravitational force on an object |
| Volume | the amount of space that an object takes up, or occupies |
| Density | a measure of the amount of mass in a given volume |
| Physical Property | a characteristic of a substance that can be observed and measured without changing the identity of the substance |
| Chemical Property | describes a substance's ability to change into a new substance with different properties |
| Physical Change | a change that affects one or more physical properties of a substance |
| Chemical Change | occurs when one or more substances change into entirely new substances with different properties |
| Law of Conservation of Mass | states that in ordinary chemical and physical changes, mass is not created or destroyed but is only transformed into different substances |
| Atom | the smallest unit of an element that maintains the properties of that element |
| Element | made up of one or more of the same kind of atom chemically combined |
| Compound | made up of different kinds of atoms chemically combined |
| Mixture | contains a variety of elements and compounds that are not chemically combined with each other |
| Pure Substance | a substance that has definite physical and chemical properties such as appearance, melting point, and reactivity |
| Heterogeneous | one that does not have a uniform composition |
| Homogeneous | ex: if you add sugar to a cup of water, the sugar dissolves. Each part of the sugar-water mixture has the same sweet taste |
| Solid | a substance with definite volume and shape |
| Liquid | a substance that has a definite volume but not a definite shape |
| Gas | does not have definite volume or shape |
| Freezing | the change in state in which a liquid becomes a solid |
| Melting | the change of state from a solid to a liquid |
| Evaporation | As liquid is warmed, its particles gain energy. Some particles gain enough energy that they escape from the surface of the liquid and become a gas |
| Boiling | a rapid change from a liquid to a gas, or vapor |
| Condensation | change of state from a gas to a liquid |
| Sublimation | change from a solid state directly into a gas |
| Deposition | the change in state from a gas directly to a solid |
