| 单词 | saturated |
| 释义 | saturated 1 (of a ferromagnetic material) Unable to be magnetized more strongly as all the domains are orientated in the direction of the field. 2 (of a solution) Containing the maximum equilibrium amount of solute at a given temperature. In a saturated solution the dissolved substance is in equilibrium with undissolved substance; i.e. the rate at which solute particles leave the solution is exactly balanced by the rate at which they dissolve. A solution containing less than the equilibrium amount is said to be unsaturated . One containing more than the equilibrium amount is supersaturated . Supersaturated solutions can be made by slowly cooling a saturated solution. Such solutions are metastable; if a small crystal seed is added the excess solute crystallizes out of solution. 3 (of a vapour) See vapour pressure. |
