Describe the movement of particles in solids, liquids, gasses, 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. |
gas | a form of matter that does not have a definite form or shape. |
melting point | temperature at which a solid changes into a liquid. |
vaporization | process in which a liquid changes into a gas. |
boiling point | the temperature at which a liquid vaporizes and changes to a gas. |
condensation | the change in state from a gas to a liquid |
sublimation | the process in which a solid changes directly into a 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 enough to completely remove electrons from the atoms to which they were bound. |
freezing point | temperature at which a liquid turns into a solid. |
