Thermal Energy

Conduction is the process by which heat energy is transmitted through collisions between neighboring molecules.Example of Conduction: Think of a frying pan set over an open camp stove. The fire's heat causes molecules in the pan to vibrate faster, making it hotter.

Conduction

Convection: is the transfer of heat through fluids (gases or liquids) from a warmer spot to a cooler spot. The particles in fluids (liquids or gases) can move from place to place when heated. Convection occurs when particles with a lot of heat energy move and take the place of particles with less heat energy.Example of Convection: Boiling water - The heat passes from the burner into the pot, heating the water at the bottom.

Convection

Radiation is energy that comes from a source and travels through some material or through space. Light, heat and sound are types of radiationExample of Radiation: A person placing their cold hands over a warm fire

Conduction, Convection, RadiationSong For Teaching About Heat Transfer Professor BoggsConduction, convection, radi-adi-ationThese are all the ways that heat can move from a locationTemperature's a risin', molecules are movingHeat will flow from hot to cold it's really not confusing at all!Talk about conduction --Heat is movin' through a spoonStir a cup of coffee ' you'll feel it pretty soonHotter solid molecules they bump into the coolAnd a wave of heat will move along conductors as a rule -Now there's convectionThat's when heat moves through the airOr some water or a substance that can move from here to thereWarmer currents rise, and cooler currents sinkBut it mixes up and evens out, it makes you want to think about...Now radiationLike the sun upon your faceIt spreads by waves of light that even move through outer spaceThe waves they hit the molecules and make them dance aroundThe darker colors do it best, at least that's what we've found!\So next time that you got a hot potato in your handIf you want to cool it down you got to understandSolids can conduct, air and water can convectBut radiation is the one that light waves can detect...http://www.songsforteaching.com/science/professorboggs/conduction-convection-radiation.htm

Thermal energy is what we call energy that comes from the temperature of matter. The hotter the substance, the more its molecules vibrate, and the therefore the higher its thermal energy.
