States of Matter
| Term | Definition |
|---|---|
| Element | A pure substance made of one only kind of atom |
| Compound | Two ore more elements together to make one element |
| Molecular formula | Shows the types and numbers of atoms combined in a singular molecular compound |
| Chemistry | The study of the properties of matter and how matter changes |
| Atom | Smallest particle of an element |
| Compound | Two or more elements together to make one element |
| Substance | A particular kind of matter with uniform properties |
| Mixture | Mixing one mixture and another mixture to make one whole mixture |
| Heterogenous mixture | The parts of the mixture are noticeably different from one another. Ex: Pizza and salsa |
| Homogenous mixture | The substance are so evenly distributed that is hard to tell one substance from another in the mixture. |
| Solution | When substances dissolve and form a homogenous mixture |
| Suspension | A heterogeneous mixture that separates into layers over time. |
| Colloid | Contains some particles that are intermediate in size. |
| Viscosity | A measure of a fluid's resistance to flow |
| Conductivity | A material's ability to allow heat to flow |
| Malleability | The ability of a solid to be hammered without shattering |
| Melting point | The temperature at which a substance changes from a solid to a liquid. |
| Boiling point | The temperature at which a substance boils. |
| Physical properties | Any characteristic of a material that can be observed or measured without changing the composition of the substances in the material. |
| Chemical properties | Any ability to produce a change in the composition of matter |
| Physical changes | The appearance or form of the matter changes but the kind of matter in the substances does not. |
| Chemical changes | a change of materials into another, new materials with different properties and one or more than one new substances are formed. |
| Types of matter | 1. Solids 2. Liquids 3. Gases 4. Plasma |
| 1. Solids | Low KE- particles vibrate but can't move Definite shape and volume Examples: Ice and Gold |
| 2. Liquids | Higher KE- particles can move around but are still close together Indefinite shape and definite volume Examples: Water and milk |
| 3. Gases | High KE- particles can separate and move throughout container Indefinite shape and volume Examples: Hydrogen and Oxygen |
| 4. Plasma | Very high KE- particles collide with enough energy to break into charged particles (+/-) Gas-Like, indefinite shape and volume Examples: Lightning and fluorescent light bulbs |
| Phase change- Solid to Liquid | Melting |
| Phase changes- Liquid to Solid | Freezing |
| Phase changes- Liquid to Gas | Evaporation |
| Phase changes- Gas to Liquid | Condensation |
| Phase Changes- Solid to Gas | Sublimation |
| Phase Changes- Gas to Solid | Deposition |
| Kinetic Molecular Theory | Tiny, constantly moving particles make up all matter |
