2 Transfer of Thermal energy Happens by two methodsParticlesWaves
3 ConductionThe transfer of thermal energy by the collisions between particles of matterExplain how a metal spoon is heated by a Bunsen burnerAir particles near flameParticles in spoon nearest flameParticles in spoon farthest from flame
4 Heat ConductorsThe rate at which conduction occurs depends upon the type of material.Heat moves faster in _____________Heat moves slower or not at all in ___________
5 ConvectionLiquids and gases are classified as fluids because _______________Convection is the transfer of thermal energy by fluidsThe movement of fluids from a _________ place to a _________ place.
6 Heat Transfer by Currents What happens to fluids as the heat up?ExpandDensityRiseAs they rise they cool off and then what happens?
7 Radiation How does the energy from the sun get to the Earth? Radiation is the energy transfer by electromagnetic wavesThese waves travel through space or matterOther examples
8 Controlling Heat Flow How do you control heat flow? How do animals in the artic control heat flow?How do animals in the desert control heat flow?What about the color of fur or skin?
9 InsulatorsInsulators are materials the resist the flow of thermal energyAir an excellent insulatorMetals are notHow does a thermos bottle work?
