Conduction

What is conduction?
Conduction is the process of thermal energy transfer without any flow of the material medium.
It is also the transfer of thermal energy between neighboring molecules in a substance due to a temperature gradient.
Conduction is most effective in solids, but it can happen in liquids and gases.
eg. a spoon in a cup of hot soup becomes warmer because the heat from the soup is conducted along the spoon.
Fun fact:
Have you ever noticed that metals tend to feel cold? Actually, they are not colder. They only feel colder because they conduct heat away from your hand. You perceive the heat that is leaving your hand as cold.
