Heat! Conduction, convection and radiation

CONDUCTION:

Transfer through direct contact of particles from item to item

CONVECTION:

Convection is a circular pattern of heat transfers, only with liquids and gases. Heat expands and then rises away from a heat source, cools down, and then continues the circular pattern.

RADIATION:

Radiation is heat transfer through electromagnetic waves. You don't touch the heat directly, waves of heat travel through space or air or other fluids.
