Question

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

Answer 1

• Physical changes are the changes where the arrangement of molecules is altered thus the state is getting changed.
• No new products are being formed and the molecular composition remains unchanged.
• Thus we can say that in physical changes the chemical properties are not changed.
• Beating Aluminium metal to make Aluminium foil is a physical change.
• This is because people can develop their products or the Aluminium foils with the Aluminium sheets during the beating, moulding, heat pressing, and fabrication process.
• In a chemical change, the molecular composition of the substance is completely altered resulting in the formation of a new product.
• These changes cannot be reversed, for example burning of wood is a chemical change.
• Thus beating of Aluminium sheet to make Aluminium foils is not a chemical change.

Therefore, Beating Aluminium to make Aluminium foil is a physical change.
