Why is it not recommended to walk dogs in the city during very hot days?

Things like the metal pot is made of atoms.

When it is heated, the atoms start to vibrate and gain energy.

The atoms transfer this energy to one another through heat.

The transfer of heat from one particle to another is called conduction

Materials like this are called conductors.

​

​Heat Transfer

​The metal pan is a good conductor of heat

In the picture, the aluminum foil creates a path for the electrons.

The electrons travel from the battery to the bulb.

The aluminum foil is also a conductor.

​

​Electric Conduction

Conductors are materials that can transmit heat or electricity with minimum resistance.

Steel, gold, copper, and seawater are good conductors.

Insulators resist the flow of heat or electricity.

In everyday life, they protect us and machines from overheating.
