Heat Transfer

conduction, convection, radiation

conduction

The heat vibrates down the metal or steel until it reaches the end, which will heat up


example: fry pan heats up using conduction, the heat of a coffee goes through the cup and you can feel it on the outside, lights heat up usinng conduction

convection

convection is 'heat rises and cold air goes down'


example: microwaves suck cold air in and turn it into heat, when theirs a fire you have to crawl along the ground because the heat rises above you

radiation

dark colours create more heat than light colours which create a lot less heat


example: dark pavers get hot and light pavers are cold, when you climb on the roof its really hot
