How Heat TransfersIn our environment, heat always moves from the hotter object to the colder object. Heat transfers through conduction, convection and radiation until those objects are the same temperatures.

ConductionConvectionRadiation

Conduction• Transfer of heat• Direct contact

The better the conductor, the more rapidly heat will transfer

Good Conductors are:Copper, silver, iron, and steel
