               Conductivity: -

               It the property of some materials for that heat or
               electricity can flow through them easily.

               The materials which can conduct heat are called
               good conductor of heat. Similarly, the materials
               which can conduct electricity, they are called good
               conductor of electricity.
               Some materials can conduct both heat and
               electricity.

               Metals like iron, copper, aluminum, silver etc are good conductor of heat as well as
               electricity. That is why utensils are generally made up of metal, they allow heat to pass
               thoroughly and cooking will be faster.

               Metals are also used for electrical appliances, as they are good conductor of electricity.


               Some materials are not allowing heat or electricity to pass through them; they are bad
               conductor.

               Wood and plastics are bad conductor. That is why they are used for the handle of utensils,
               switch board etc.
