WebFeb 2, 2024 · Students are familiar with everyday examples of freezing, melting and boiling, but are likely to think temperature always falls during freezing and rises during melting or boiling. The reality is not so simple. Some temperature changes are counter-intuitive, as can be shown by simple investigations. WebMay 20, 2024 · The effect of adding a solute to a solvent has the opposite effect on the freezing point of a solution as it does on the boiling point. A solution will have a lower freezing point than a pure solvent. The freezing point is the temperature at which the liquid changes to a solid. At a given temperature, if a substance is added to a solvent (such ...

WebFeb 11, 2024 · The melting point of a solid is the temperature at which the vapor pressure of the liquid phase and the solid phase are equal and at equilibrium. If you increase the temperature, the solid will melt. If you decrease the temperature of a liquid past the same temperature, it may or may not freeze! This is supercooling and it occurs with many ...
