S8P1.c
describe the movement of particles in solids, liquids, gases, and plasma states
Term | Definition |
---|---|
State of matter | the physical forms of matter which include solid, liquid, and gas |
Solid | the state of matter in which the volume and shape of a substance are fixed |
Liquid | the state of matter that has a definite volume but not a definite shape |
Gas | a form of matter that does not have a definite shape or volume |
Melting Point | temperature at which a solid changes to a liquid |
Vaporization | process in which a liquid changes to a gas |
Boiling Point | temperature at which a liquid vaporizes and changes to a gas |
Condensation | the change of state from a gas to a liquid |
Freezing point | temperature at which a liquid changes into a solid |
Sublimation | the process in which a solid changes directly into gas |
Phase-change-diagram | drawing that shows the relationships among temperature and changes of state |
Plasma | a state of matter that forms when temperatures are high enough to completely remove electrons from the atoms to which they were bound |
