Conduction
• Definition:
The transfer of __________
through a material by ___________
__________.
• Examples:•
•
direct contactheat
A metal spoon gets hot quickly in hot cocoaAn iron heats up the material it comes in contact with.

Heat transfer by Conduction
•Note that in metals, heat is transferred through free-moving electrons, and in other substances through moving atoms.
