States of matter
Liquid
State symbol: (l)
Liquids have fixed volume but no shape
State symbol (aq): element dissolved in liquid
vibrational motion, low energy
Solid
State symbol: (s)
Solids have a fixed shape and volume
moderate energy, rotational and vibrational motion
Gas
State symbol: (g)
Gases have neither a fixed volume nor shape
gas laws
Combined Gas law
P1V1/T1 = P2V2/T2
Boyle's law
P1V1 = P2V2
Charles' law
V1/T1 = V2/T2

solid to liquid = melting (heat in to the solid)
liquid to solid = freezing (heat leaves the liquid)
liquid to gas = vaporization (inc.boiling and evaporation) (heat in to the liquid)
gas to liquid = condensation (heat leaves the gas)
solid to gas = sublimation (heat in to the solid)
