- Molarity : Chemical term for concentrations of solutions, having units of moles/liter.
- Molality : Concentration unit, moles/kilogram, useful for measuring solvent properties.

- Partial pressure : The pressure which each gas in a gas mixture would have if it alone occupied the same volume at the same temperature.
- Parts-per notation : Notation used in science and engineering, to denote dimensionless proportionalities in measured quantities such as proportions at the parts-per-million (ppm), parts-per-billion (ppb), and parts-per-trillion (ppt) level.
- Relative volatility : A measure that compares the vapor pressures of components in a liquid mixture that is widely used in designing distillation and similar separation processes.
