How many ways are there to transfer heat? How can thermal energy (heat) be transferred?
Where does the heat come from? Where does the heat go? How long will the heat last?
Transfer of Heat Notes 2-2-12 Heat can move 3 ways…… Any idea how? Convection! Radiation! Conduction!
Convection The transfer of heat in a gas or liquid by movement of currents. Warm air rises and cool air sinks making a current. Ex: Heat leaves a coffee cup as the currents of steam and air rise. The warmed matter (air) is being transferred.
