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.
I believe it is physical because you are not changing the chemical compound.

Boiling point and freezing point are examples of physical properties. They describe the characteristics of a substance that can be observed or measured without changing the chemical composition of the substance.
It is a physical property because it's not changing the chemical structure of the water, it's just changing how it looks/ physical appearance. :)

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.
Freezing is a physical change because the substance that freezes does not change its chemical composition.
physical, ice is still H2O
yes it is.

Freezing point is a physical property. It is the temperature at which a substance changes from a liquid to a solid state under standard atmospheric pressure. Physical changes involve a change in state without altering the chemical composition of a substance.
Yes, melting/freezing point is a physical property.
Hardness is a physical property that describes the ability of a substance to resist deformation. Ability to react with oxygen is a chemical property that describes how a substance interacts with oxygen. Color is a physical property that describes the visual appearance of a substance. Freezing point is a physical property that indicates the temperature at which a substance changes from a liquid to a solid.
