WebJul 19, 2024 · 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 as water), the solute-solvent interactions prevent the solvent from going into the solid phase. WebYou will determine the freezing point by making a plot of temperature versus time and fitting two straight lines to the data. This is done by splitting the temperature data into two columns in Excel. The first column will be the temperature readings in which the difference between successive readings is greater than 0.5°C.
