State of Matter | the physical forms of matter which are solid,liquid and gas |
Solid | the state of matter in which the volume are the shape of a substance are fixed |
Liquid | composed of molecules that move freely among themselves but do not tend to separate like those of gases; neither gaseous nor solid. |
Gas | a form of matter that does not have definite volume or shape |
Melting Point | the temperature at which a solid changes to a liquid |
vaporization | process in which a liquid changes to a gas |
boiling point | the temperature at which a liquid vaporizes and changes to a gas |
condensation | the change of state from a gas into a liquid |
freezing point | the temperature at which a liquid changes to a solid |
sublimation | process in which a solid changes directly into a gas |
phase change diagram | drawing that shows the relationship among temperature and changes of state |
plasma | a state of matter that forms when temperatures are enough to completely remove electrons from the atoms to which they were bound |
