“depression of freezing point”的概念、定义、习题解题方法及翻译-物理辞典

单词	depression of freezing point
释义	depression of freezing point The reduction in the freezing point of a pure liquid when another substance is dissolved in it. It is a colligative property - i.e. the lowering of the freezing point is proportional to the number of dissolved particles (molecules or ions), and does not depend on their nature. It is given by δt = K_fC_m , where C_m is the molar concentration of dissolved solute and K_f is a constant (the cryoscopic constant ) for the solvent used. Measurements of freezing-point depression (using a Beckmann thermometer) can be used for finding relative molecular masses of unknown substances
