Heat Transfer

Conduction, Convention, Radition

Conduction

Heat can be transferred by conduction. When an object is heats, the particles in the object begin to vibrate. These vibrations are passed on through the object, transferring the heat from one end to the other.


Examples of conduction in everyday life is when a saucepan transfers heat through the particles of the metal all through the sauce pan and when someone touches the saucepan it would be hot.

Convection

Heat can be transferred from one place to another via convection. In convection hotter particles rise and cooler particles fall circulating heat.


Examples of conduction in everyday life is when the boiling water heat passes from the burner into the pot, heating the water at the bottom. Then, this hot water rises and cooler water moves down to replace it, causing a circular motion.
