What happens to a substance when it becomes oxidized reduced

When copper is heated to temperatures of around 870-980 degrees Celsius, it will begin to oxidize—meaning that it will react with oxygen from the air to form copper oxide. The oxidation process creates two distinct layers on the surface of the copper—a thin outer layer of black copper oxide and an inner layer of red-brown cupric oxide.
