WebMelting and freezing points are physical properties of pure substances. In this lab activity, you will determine the melting point and the freezing point of lauric acid. Your instructor will use heating and cooling curve to show how temperatures change during the melting and freezing of water. Kinetic and potential energy changes will be discussed. WebAug 8, 2024 · The freezing point depression is the difference in temperature between the freezing point of the pure solvent and that of the solution. On the graph, the freezing point depression is represented by ΔTf. Figure 16.13.1: The vapor pressure of a solution (blue) is lower than the vapor pressure of a pure solvent (pink).
