Hardness a physical or chemical
When fruit rots there are various kinds of changes, one of which is that it becomes softer and ultimately liquifies. Hardness is a physical characteristic, hence if it changes, that is a physical change.
It's a physical property 😀😃
It is a physical change.Density is not a chemical property. Instead, it is a physical property.
Physical change is a change in the structure. Chemical change is a change in the composition. Melting is a physical change. Complexing is a chemical change.
Hardness is a physical change. It does not involve a change in the chemical composition or structure of a substance, but rather a change in its physical properties such as strength or resistance to deformation.
The hardness and density of zinc are physical properties, as they do not involve any change in the chemical composition of the substance. Changes in physical properties can be observed without altering the chemical identity of the material.
A chemical change such as density, color , hardness

Hardness a physical or chemical
physical property
This is False. The colour has to change to be a chemical change/property. If it stays the same, it is physical. Hardness is an example of a physical property. (ex. If I melt a piece of hard steel, it will become soft, liquid probably, but it isn't hard anymore, this change is reversible, therefore a physical change/property)
Cutting a diamond is a physical change. It involves breaking the diamond into smaller pieces through mechanical means without altering the chemical composition of the diamond itself.
physical property
Physical change is the change in which only physical properties changes ,like color, hardness, density etc. Chemical changes affect the composition as well as chemical properties of matter and result in formation of new substance. Examples of chemical changes are : Burning of coal Burning of Paper Electrolysis of water
