Abstract

When solute molecules are confined, they exert a positive pressure on the barrier. If this is simply the free solvent surface, balance of forces requires the solvent to attain an equal negative hydrostatic pressure. This offers a sufficient explanation for the reduction of the vapor pressure over a solution.

摘要

当溶质分子受到限制时，它们会对屏障施加正压力。如果这仅仅是自由溶剂表面，力的平衡要求溶剂达到相等的负静水压。这为溶液上方蒸气压的降低提供了充分的解释。
