Conduction convection radiation
Transcript of Conduction convection radiation
your body Can you think of anything else? transfer of heat in waves of energy without needing matter light colors radiate heat dark colors absorb heat Which is why summer fashion has pale colors, and winter has dark. but what happens as they heat up? the moleules at the end start to vibrate faster they hit their neighbor, transfering a bit of their kinetic energy the neighbor hits it's neighbor
thus the transfer of energy down the solid all metals conduct energy Since is the movement of molecules heat There is no such thing as the transfer of COLD! Heat either enters or leaves through a transfer of energy by molecules moving faster (gaining heat)
or molecules moving slower (giving heat away) Therefore always moves from hot to cold heat or from fast molecules to slow molecules their lattice work pattern allows for the easy transfer of energy Not every solid has the ability to conduct energy. things that prevent or slow conduction are called insulators so they are called conductors examples of insulators: Why is this important to you? Can you think of other examples of convection in your life? transfer of energy through a solid energy transfer through liquids and gases How could you use this knowledge? this is called radation
