Is freezing chemical or physical property?

Answer 1

I would say that freezing point is a boiling property because there is no scientific evidence to suggest that it is or indeed ever will be a chemical property. Freezing point is a chemical reaction. Therefor this is a debatable question. Different people may have different views. This is mine."Freezing point" is usually termed as "melting point" in scientific circles. Melting point is defined as the temperature at which the solid and liquid phase of a substance coexist at equilibrium under the pressure of their own vapors. Ice and water coexist at equilibrium at temperature of 32 degrees F when only their own vapor pressures are acting upon them. However, the temperature difference at atmospheric pressure is negligible. As you can see, melting point (freezing point) only depends on the physical conditions acting on the substance, therefore, melting point (freezing point) is a physical property.

Melting point is effected (lowered) by the addition of other molecules or ions to the substance. This effect is physical because it depends only upon the number of particles (molecules etc) added and no chemical reaction is required.

Answer 2

The freezing point of a substance is the same as the melting point. They are both physical properties of matter since when a substance changes from a liquid to a solid, a physical change has occurred.

Answer 3

No. The freezing point of a substance is a physical property.

Answer 4

The freezing point of water is considered to be a physical property. This is because the chemical composition does not change when the shape does.

Answer 5

No, the freezing point or melting point is not a chemical property but a physical property.

Answer 6

Freezing point is a physical property.

Answer 7

physical property

Answer 8

no it,s not
