viscosity is a physical characteristic not a physical change. it is the thickness of a substance
physical changes would be if it turned from solid into a liquid.
for example a chocolate bar goes through a physical change when it becomes melted chocolate.
Viscosity changes when another agent is added to a fluid. For example, paint has a fairly thick viscosity and if intending to apply it using a spray gun, one would need to add thinners, varsol, or turpentine to the paint to thin it out so that it will pass through the gun. Thus changing the viscosity.
it is a 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.
Viscosity is a physical property of a substance, which describes its resistance to flow or deformation. It is determined by the intermolecular forces within the substance and is not a result of any chemical changes or reactions.

A physical change
Physical change of the paint, not the door.
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.

Physical change
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.
