Heat can move by CONDUCTION

CONVECTION

RADIATION

Conduction moves heat between objects that are touching.

Convection moves heat up and down through air or water.

Radiation moves heat out in all directions as waves through space.

Examples of conduction are:

* touching a hot pot

* a spoon in a cup of hot tea

* a pan on the stove.
