state of matter
| term | denintion |
|---|---|
| solid | state of matter in which the particles of matter are the closest |
| liquid | state of matter in which the particls are free to move over, under and around one around |
| gas | state of matter in which the particles are moving the fastest and are the farthest away from each other |
| plasma | state of matter that is achieved under very high tempertuers |
| endothermic | physical change in which eneryg is abosh temperature of the substance changes |
| exothermic | physical change in which energy is release the temperature of the substance changes |
| kinetic-molecular theoy | explains that differences in the states of matter are caused by how fast the atoms in a substance are moving |
| melting | the phase change from a solid to a liquid material to must gain energy |
| melting point | the temperature at which a substance begins to melt ex: 32 f 0 c |
| freezing | the phase change from a liquid to a soild, material must lose energy |
| freezing point | the temperature at which a substance begins to freeze ex: 32 f 0c |
| vaporiztion | phase change from a liquid to a gas, material must gain energy |
| evapoation | phase change from a liquid to a gas at the surface of a liquid below the boiling point |
| boiling | the phase change from a liquid to a gas throughout the entire liquid |
| boiling point | the temperture at which a substance begins to boil ex:212 f 100c |
| condensation | the change in a phase from gas to a liquid, material requires a loss of energy |
| sublimation | (the change in a phase from a solid to a gas without going trough the liquid phase |
| deposition | the phase change from solid to gas |
