The freezing point depression equation is Tf i Kf m, where Tf is the change in freezing point, i is the van't Hoff factor, Kf is the cryoscopic constant, and m is the molality of the solution.
The change in the freezing point of a solvent by the addition of a solute is called freezing point depression. This phenomenon occurs because the presence of the solute disrupts the crystal lattice formation of the solvent, requiring a lower temperature for freezing to occur.
Simple: a transformation from a solid to a liquid.
The freezing point is a physical property because it describes a characteristic of a substance (temperature at which it freezes) without changing the chemical composition of the substance. When a substance freezes, it undergoes a physical change from a liquid to a solid, not a chemical change.
- Melting point change. ^.^
Melting is equivalent to freezing: a temperature when a solid become a liquid.

you must reach its melting point or freezing point or boiling point.
Changing the pressure can affect the freezing point of a substance. Generally, an increase in pressure will lower the freezing point, while a decrease in pressure will raise the freezing point. The presence of solutes or impurities in the liquid can also change the freezing point.

It is a physical change.
They can change by lowering the freezing point.
The freezing point is a physical change because the substance is the same before and after only changing its form.
