17. state of matter | the physical form of matter, which include solid, liquid, and gas |
18. solid | the state of matter in which the volume and shape of a substance are fixed |
19. liquid | the state of matter that has a definite volume but not a definite shape |
20. gas | a form of matter that does not have a definite volume or shape |
21. melting point | temperature at which a solid changes to a liquid |
22. vaporization | process in which a liquid change to a gas |
23. boiling point | temperature at which a liquid vaporizes and changes to a gas |
24. condensation | the change of state from a gas to liquid |
25. freezing point | temperature at which a liquid changes into a solid |
26. sublimation | the process in which a solid changes directly into a gas |
27. Phase-change diagram | drawing that shows the relationships among temperature and changes of state |
28. plasma | a state of matter that forms when temperatures are high enough to completely remove electrons from the atoms to which they were bound |
