In a solid, the particles are held tightly together. So when one particle vibrates, it bumps into other particles nearby and quickly passes the vibration on. 

Particles which vibrate faster than others pass on their kinetic energy. These particles then vibrate faster themselves. 

This process continues throughout the solid and gradually the extra kinetic energy is spread all the way through the solid. This causes a rise in temperature at the other side.

CONDUCTION OF HEAT is the process where vibrating particles pass on extra kinetic energy to neighbourind particles.

Metals are really good conductors of heat - thats why theyre used for saucepans. Non-metals are good for insulating things e.g. for saucepan handles. 

Liquids and gases conduct heat energy more slowly
