Beating aluminium to make Aluminium foil is a physical or chemical change?

Beating aluminum to make aluminum foil is a physical change, not a chemical change.

A physical change involves altering the physical properties of a substance without changing its chemical composition. In this case, when aluminum is beaten to create aluminum foil, it is still chemically aluminum. The beating process simply changes its shape and possibly its thickness, but the chemical identity of the material remains the same.

In contrast, a chemical change (or chemical reaction) would involve a change in the chemical composition of the substance, which results in the formation of new substances with different properties. This is not the case when aluminum is beaten to make aluminum foil, so it is considered a physical change.
