- Melting point change. ^.^
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.
The change in freezing point of water can be calculated using the formula: ΔTf = Kf * m, where Kf is the freezing point depression constant (1.86 °C kg/mol for water) and m is the molality of the solution. From the given masses, you can calculate the molality of the solution and then use it to find the change in freezing point.

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.
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.
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.
Simple: a transformation from a solid to a liquid.
Another name for freezing point is melting pointsince the temperature at which a substance freezes is also the temperature at which it melts, going in the other direction.Freezing point could also be referred to as congelation point.
