3. (Chemistry) The state in which a substance contains no multiple bonds and thus is incapable of undergoing additional reactions.
4. (Electronics) A condition when an increase in base current will not produce an appreciable change in the collector-emitter voltage.
The operation of supersaturating, or the state of being supersaturated.
In chemistry, the state of a solution that has a higher concentration of solute than would normally be obtained in a saturated solution.
Many solutes have a higher solubility at high temperatures. If a hot saturated solution is cooled slowly, sometimes the excess solute does not come out of solution. This is an unstable situation and the introduction of a small solid particle will encourage the release of excess solute.
