A sheet of copper can be pounded into a bowl a physical or chemical change?
Pounding a sheet of copper into a bowl is a physical change because the copper is still the same substance before and after the change. The change in shape does not alter the chemical composition of the copper.
Is a piece of copper cut in half a physical or chemical change?
Cutting a piece of copper in half is a physical change because it only alters the physical appearance of the copper without changing its chemical composition.
Is copper sulphate a physical change or chemical?
Copper sulfate dissolving in water is a physical change as no new substance is formed. However, if copper sulfate is heated to decomposition, it would be a chemical change because a new substance is formed.
Is melting copper an example of chemical change?
It can be. Temperature increases usually induce physical changes in the broad sense. If the change in temperature merely induces a state change (for instance, the copper is melted - becoming a liquid) then it is purely a physical change. Presuming that heating will occur in the presence of air, it will also increase the rate of oxidation and, therefore, be indirectly inducing a chemical change.
Is copper conducts electricity chemical or physical change?
Copper conducting electricity is a physical change because it involves the movement of electrons within the material, without changing its chemical composition.
