- The volume of a gas is inversely proportional to its pressure if temperature is held constant
- The ratio of the sine of an angle of incidence to the sine of the angle of refraction is a constant.
- The solubility of a gas in a liquid is directly proportional to the partial pressure of the gas
- When a substance is dissolved in a solvent, the solution formed will have a lower freezing point, higher boiling point, and less vapor pressure than the pure solvent.
