All steels are good conductors that heat and they are different in conducting the heat, which way that some metals conduct the heat quicker than the other, The warmth makes us comfortable and also helps us to prepare ours food and it is one interesting kind of energy.

You are watching: Explain why air is not a good conductor of heat

Heat conductors

Some materials enable the heat to flow through them and they are well-known as great conductors of warmth or warm conductors such as iron, aluminum, copper, silver, brass, lead and also stainless steel.

The metals are better conductors due to the fact that they contain free electrons, the electrons relocate through the metal easily, They acquire the kinetic energy from collisions with hot atoms and also pass ~ above the energy when lock collide v cold atoms, This transfers the heat an ext quickly.

Leaving the spaces in between the railway bars which room made of steel to avoid the train mishaps where steel is a great conductor the heat, So, the expands and also twists by the heat.


Metals are great conductors the heat.

The various metals different in conducting the warmth where copper conducts the heat faster than aluminum and aluminum conducts the heat much faster than iron.

Heat insulators

Some products do not allow the warm to circulation through them and they are well-known as negative conductors of heat or heat insulators, The insulators are poor conductors that heat, The poor conductors are good insulators and they are materials that the heat deserve to not take trip through.

Heat insulators such together the wood, the glass, the paper, the wool, the rubber, the liquids, the plastic, the cork, styrofoam, the vacuum and also the gases especially the air.

The people advantage from the air together an insulator product in maintaining the warmth in the cold countries, the waiting is offered in make the insulating glass windows.

The insulating glass window is make by bonding two glass sheets and leaving a an are filled through the air between them to stop the leakage the the heat.

Usages of good and negative conductors the heat

Aluminum, copper and stainless steel are an excellent heat conductors as they space metals, castle are offered in making food preparation pots and also the kettles the are used in the houses and the factories.

The food preparation pots get heated increase quickly and also the food have the right to be cooked effectively in much shorter time, Plastic and also the wood are warmth insulators, they are supplied in make the handle of the cooking pots, the iron and also the kettles, They assist in holding them comfortably.

The wool is a heat insulator which is offered in make the hefty blankets and the wooden clothes, So, lock are provided in the winter to save the body warm and also prevent the leakage the the heat, The hair and also the hair of animals are bad conductors the heat and also they defend them native cold.

The vehicles transporting inflammable materials such together petrol space covered v the materials of poor conductors of warm to protect against petrol from heater up and also catching the fire.

Building materials like the bricks, the asbestos and also the mud are bad conductors of heat, they perform not permit heat and also cold to pass through the wall surfaces of the bricks.

The structure materials keep the dwellings warm in the winter and also cool in the summer and also the roof sheds are made the asbestos for the very same reason.
