This is a physical change. There is nothing that changes the components of either the diamond or the glass when the diamond is used to scratch glass.
A physical change
Physical change of the paint, not the door.
Chemical change: the composition of the initial reactants is changed. Ex.: thermal decomposition of calcium carbonate. Physical change: the composition is not changed during this transformation. Ex.: boiling of water.
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
A physical change is reversible, a chemical change is not.
This is a physical process.
Diamonds cutting grass would be considered a physical property. This is because the ability to cut grass is a physical characteristic of the diamond based on its hardness and structure, rather than a chemical change in the diamond itself.

it is a chemical change
An acid is a chemical compound, not a physical or chemical change.
It is a physical change.Density is not a chemical property. Instead, it is a physical property.
Crushing charcoal into powder is a physical change, as it alters the size and shape of the charcoal without changing its chemical composition.
Physical change
Chemical broooooooooooooooo niga
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.
