3 Heat Transfer Pg. 61 Heat moves from areas of higher temperature to areas of lower temperature. Insulators prevent the transfer of heat and conductors transfer heat quickly. There are 3 different ways that heat can move: conduction, convection and radiation.

4

5 1. Conduction - -Heat transfered when two objects come into contact.
The heat travels from the warmer object to the colder object.

6 2. Convection- -the transfer of heat through moving air or fluids.

7 Convection occurs because there is a density difference that results from a temperature difference.
Colder substances are more dense and drop and warmer substances are less dense and rise. This creates a convection current of warmer air or fluid that carries heat to the colder area or object.

8 3. Radiating energy- heat moving over distance whether or not there is a medium.(doesn’t need to touch) -All objects with a temperature above absolute zero give off radiant energy. -This is why the Earth can be heated by a sun that is million km away.
