    State of matter in which volume and shape of a substance are fixed (67)
  2. Liquid
    State of matter that has a definite volume, but not a definite shape (68)
  3. Gas
    State of matter that does not have a definite volume or shape (69)
  4. Evaporation
    Change of a substance from a liquid to a gas (76)
  5. Condensation
    Change of state from a gas to a liquid (77)
  6. Melting point
    Temperature at which a substance changes from a solid to a liquid; physical property; different substances have different melting points (75)
  7. Boiling
    Temperature at which a liquid boils (76)
  8. Sublimation
    The process in which a solid changes directly into a gas; endothermic change because energy is gained by the substance as it changes state (78)
  9. Melting

    Combination of two or more substances that are not chemically combined (98)
  14. Physical change
    Change of matter from one form to another without a change in chemical properties (48)
  15. Absolute zero
    Temperature at which molecular energy is at a minimum; 0 K; -273.16°C (277)
  16. Boiling point
    Temperature at which a liquid boils (76)
  17. Density
    Ratio of the mass of a substance to the volume of the substance (26, 45)
  18. Plasma
    State of matter in which electrons have been removed from atoms; made up of ions and electrons
  19. Vaporization
    The process of becoming a vapor; Conversion of a solid or liquid into a gas; Three types of vaporization are sublimation, evaporation, and boiling
