Answer 1

Answer:

electricity is passed through the water form a complete circuit

during electroplating metal is deposited as painting or colouring

iron is coated with air water and sunlight deform the resting

Answer 2

Explanation:

When electricity is passed through water the gases dash and dash are released.

When electric current is passed through water , it decomposes to give hydrogen gas and oxygen gas.

During electroplating, metal is deposited at the

As the name suggests, the process involves depositing material using an electric current. This process results in a thin layer of metal being deposited onto the surface of a workpiece called the substrate. Electroplating is primarily used to change the physical properties of an object.

Iron is coated with dash

to protect it from rusting.

zinc

Galvanization is the process of applying a protective layer of zinc on a metal. It is a very common method of preventing the rusting of iron. This can be done by dipping the metal to be protected in hot, molten zinc or by the process of electroplating. Zinc is a relatively cheap metal that sticks to steel easily.
