solid
state of matter with definite shape and definite volume
liquid
state of matter with NO definite shape but has a definite volume
gas
state of matter with NO definite shape and NO definite volume
melting
the change in state from a solid to a liquid
freezing
the change in state from a liquid to a solid
evaporating/evaporation
the process that occurs when VAPORIZATION takes place ONLY at the SURFACE;(change in state from liquid to gas at surface)
boiling
the process that occurs when VAPORIZATION takes place INSIDE a liquid as well as on the SURFACE; (change in state from liquid to gas throughout the liquid)
condensing/condensation
change in state from a gas to a liquid
vaporizing/vaporization
change in state form a liquid to a gas (can describe either evaporating or boiling)
boiling point
the temperature in which a liquid becomes a gas
melting point
the temperature in which a solid becomes a liquid
kinetic theory
everything is made of moving particles
