| Question | Answer |
|---|---|
| Solid | A state of matter (particles that don't move,they are so close together that when they try to move they just calmly vibrate) |
| Liquid | A state of matter (particles that move and are a far distance from each other) |
| Gas | A state of matter (particles that are moving really fast,bouncing off the walls, and becomes it's form when water gets hot) |
| Plasma | An ionized gas consisting of positive ions and free electrons in proportions resulting in more or less no overall electric charge, typically at low pressures or at very high temperatures |
| Colloid | A homogeneous, noncrystalline substance consisting of large molecules or ultra microscopic particles of one substance dispersed through a second substance |
| Phase change | When a substance changes from one state, or phase, of matter to another we say that it has undergone a change of state, or we say that it has undergone a change of phase |
| Particle | A minute portion of matter |
| Melting point | The temperature at which a given solid will melt |
| Freezing point | The temperature at which a liquid turns into a solid when cooled |
| Boiling point | The temperature at which a liquid boils and turns to vapor |
| Evaporation | Evaporation is a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance |
| Condensation | The conversion of a vapor or gas to a liquid |
| Volume | The amount of space that a substance or object occupies, or that is enclosed within a container, especially when great |
| Mass | A coherent, typically large body of matter with no definite shape |
| Density | The degree of compactness of a substance |
| Pure substance | A material that is composed of only one type of particle; examples of a pure substance include gold, oxygen and water |
| Atom | The basic unit of a chemical element |
| Molecule | A group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction |
| Element | A part or aspect of something abstract, especially one that is essential or characteristic |
| Compound | A thing that is composed of two or more separate elements; a mixture |
