Conduction is the transfer of heat energy between two objects in contact with each other. It occurs when the atoms or molecules of one object vibrate and collide with the atoms or molecules of the other object, transferring their energy. The rate of heat transfer by conduction depends on the temperature difference between the two objects, the surface area in contact, and the material of the objects.

Example: When you touch a hot stove, heat from the stove is transferred to your hand through conduction. The atoms or molecules in the stove vibrate faster than those in your hand, so when they collide with your skin, they transfer their energy and your hand starts to feel warm. The larger the surface area of your hand that is in contact with the stove, the faster the heat will be transferred. The type of material the stove is made of also affects the rate of heat transfer. Metals are good conductors of heat, so a metal stove will transfer heat faster than a wooden stove.
