| Question | Answer |
|---|---|
| Solid | State of matter in which the particles of matter are closet together, having a definite shape and volume. |
| Liquid | State of matter in which the particles are free to move over, under, and round one another, particles are farther apart then solid, no shape but a definite volume. |
| Gas | State of matter in which particles are moving the fastest and are the furthest away from each other, no definite shape or volume. |
| Plasma | State of matter achieved under very high temperatures, no definiate shape, atoms have been ripped apart. |
| Kinetic Molecular Theory | Explains that differences in states of matter are caused by how fast the atoms in the subtance are moving. |
| Endothermic | Physical change in which energy is absorbed, the temperature of the substance changes. ENDO = IN. |
| Exothermic | Physical Change in which the energy is released, the temperature of the substance changes.EXO = OUT |
| Melting | A Phase change from a solid to a liquid, material must gain energy, temperature increases. |
| Melting Point | The temperature at which a substance begins to melt. 32 F, 0 C |
| Freezing | The pahse change from a liquid to a solid, material must lose energy, temperature decreases. |
