Zinc has a hardness on the Mohs scale of 2.5 and a density of 7.13 at 25 is it physical or chemical change?
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.
Is cutting a diamond a physical or chemical change?
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.
Is peeling an apple a physical or chemical change?
it is a chemical change
Is crushing charcoal into powder a physical or chemical change?
Crushing charcoal into powder is a physical change, as it alters the size and shape of the charcoal without changing its chemical composition.

What is it example of physical property?
A chemical change such as density, color , hardness
A characteristic of a substance that does not involve a chemical chance such as density color or hardness?
Physical Change
A characteristc of a substance that does not involve a chemical change such as density color or hardness?
physical property
Is it able to conduct a physical or chemical?
Hardness a physical or chemical
Is color and hardness examples of chemical properties?
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)
Is hardness chemical properties or physical?
physical property
Is cutting a diamond a physical or chemical change?
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.
Is hardness a chemical or a property?
physical property
How is an chemical change differs from a physical change?
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
Is fruit rotting chemical or physical?
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.
