单词 elevation of boiling point
释义 elevation of boiling point
An increase in the boiling point of a liquid when a solid is dissolved in it. The elevation is proportional to the number of particles dissolved (molecules or ions) and is given by δt = kBC, where C is the molal concentration of solute. The constant kB is the ebullioscopic constant of the solvent and if this is known, the relative molecular mass of the solute can be calculated from the measured value of δt. The elevation is measured by a Beckmann thermometer. See also colligative properties
