A solution is formed by the mixture of a solute and solvent. A saturated solution is one that contains as much solute in it that it can dissolve at a particular temperature . Any further addition of solute or reduction in temperature of solution will result in a super-saturated solution. This is because the solute will not dissolve when more solute is added and the solute will crystallize out when the temperature is reduced.
An unsaturated solution is one which contains less than the amount of solute it can dissolve at a specified temperature. For example, if a solution of sodium chloride would require 50 g of salt to saturate it, dissolving 40 g of salt will make it an unsaturated solution.
However a colloidal solution is one in which is suspended throughout a liquid. the substance is uniformly dispersed around the liquid.
A warm front is also defined as the transition zone where a warmer air mass is replacing a cooler air mass Dew point: The point at which air saturated with water vapor produces condensation which forms dew.
In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues and organs that are specialized for particular body functions.
