In this video explains Malleability:Place any one metal on a block of iron and strike it four or five times with a hammer. Observe the change in the shape of the metal?You will find that some metals can be beaten into thin sheets. This property is called malleability. Gold and silver are the most malleable metals.Ductility:The ability of metals like iron,copper and aluminium to be drawn into thin wires is called ductility.Gold is the most ductile metal. From one gram of gold we can be drawn a wire of 2 km length. Can you name some metals that are used for making cooking vessels?Let us do the experimental activity to find out the answer.
