Temperature- a measure of the amount of
kinetic energy in a substance
Heat- a transfer of energy between two objects due to a difference in temperature Heat always moves from hot to cold
Temperature vs. Heat

Conduction Convection Radiation
3 Ways Heat can be Transferred

The transfer of heat (energy) from one
substance to another substance that is touching it It is most effective in solids, but can happen in liquids
Fun fact: Have you ever noticed that metals tend to feel cold?
Believe it or not, 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
Conduction

The transfer of heat (energy) by the
movement of matter. Happens mostly in gas and liquids This happens with currents Colder matter (more dense) sinks below warmer
matter and pushed warmer matter up Have you ever heard of the saying “warm air
rises” Why does colder matter sink? (hint: use
kinetic energy, molecules, and density)
Convection

Electromagnetic waves directly transport
energy through space Done without the help of fluids or solids Travel in waves
Radiation

This causes trade winds, westerlies, and easterlies that affect major weather patterns. For example: The ITCZ near
the equator most often has clouds and rain. This is also where rainforests are.
