Köhler curves showing how the critical diameter and supersaturation are dependent upon the amount of solute. It's assumed here that the solute is a perfect sphere of sodium chloride with a dry diameter Dp. Köhler theory describes the vapor pressure of aqueous aerosol particles in thermodynamic equilibrium with a humid atmosphere.
Saturation (magnetic), the state when a magnetic material is fully magnetized; Saturated fluid or saturated vapor, contains as much thermal energy as it can without boiling or condensing Saturated steam; Dew point, which is a temperature that occurs when atmospheric relative humidity reaches 100% and the air is saturated with moisture
Hence the determination of the expansion ratio, relevant to the calculation of the mass flow through the nozzle, must be done using an adiabatic index of approximately 1.3, like that of the superheated steam, instead of 1.135, which is the value that should have to be used for a quasi-static adiabatic expansion in the saturated region.

The solubility of a specific solute in a specific solvent is generally expressed as the concentration of a saturated solution of the two. [1] Any of the several ways of expressing concentration of solutions can be used, such as the mass, volume, or amount in moles of the solute for a specific mass, volume, or mole amount of the solvent or of the solution.
Fick's first law relates the diffusive flux to the gradient of the concentration. It postulates that the flux goes from regions of high concentration to regions of low concentration, with a magnitude that is proportional to the concentration gradient (spatial derivative), or in simplistic terms the concept that a solute will move from a region of high concentration to a region of low ...
The concentration of the solute in a saturated solution is known as the solubility. Units of solubility may be molar (mol dm −3) or expressed as mass per unit volume, such as μg mL −1. Solubility is temperature dependent. A solution containing a higher concentration of solute than the solubility is said to be supersaturated. A ...
Making a saline water solution by dissolving table salt in water.The salt is the solute and the water the solvent. In chemistry, a solution is defined by IUPAC as "A liquid or solid phase containing more than one substance, when for convenience one (or more) substance, which is called the solvent, is treated differently from the other substances, which are called solutes.
c is the instantaneous solute concentration, c * is the solute concentration at saturation, (c − c *) is also known as supersaturation, n is an empirical exponent that can be as large as 10, but generally ranges between 3 and 4.
