Day 51: Heat Transfer

Are you trying to remember the three main types of heat transfer? Think of hot dogs!

CONDUCTION:
Heat is transferred through direct contact

* A pan is hot to the touch
* A spoon sitting in a hot pan will also get hot

CONVECTION:
Heat is transferred in a circular motion in air or in liquid, where the warm rises to the top and forces the cool down and closer to the heat source

* Air conditioning and heating in a home
* Boiling water/Cooking over the stove

RADIATION:
Heat is transferred by electromagnetic waves

* Sun
* Microwaves
* Radiant heat
