Heat Transfer Conduction, Convection and Radiation :

Heat Transfer Conduction, Convection and Radiation

To Make Foldable::

To Make Foldable: 1. On the short side of the paper, fold it down an inch. 2. Now fold it in half, hamburger style. 3. Now fold it in 1/3. Conduction Convection Radiation Heat Transfer Examples Definition Examples Definition Examples Definition Outside of Foldable Inside of Foldable

Thermal Energy Transfer:

Thermal Energy Transfer Thermal energy transfer is heat moving from a warmer object to a cooler object . This is known as thermal energy transfer.

How is Heat Transferred?:

How is Heat Transferred? There are THREE ways heat can move. Conduction Convection Radiation

CONDUCTION:

CONDUCTION Heat is transferred through direct contact.

Have you ever…:

Have you ever… touched a metal spoon sitting in a pan of boiling water only to be surprised by HOW HOT it is??

EXAMPLE OF CONDUCTION:

EXAMPLE OF CONDUCTION A piece of cheese melts as heat is transferred from the meat to the cheese ( Contact )

CONVECTION:

CONVECTION Heat is transferred by currents within the fluid or gas. Convection = VENTS (through air and liquid particles) Convection moves in a circular pattern

Examples of Convection::

Examples of Convection: Have you ever noticed that the air near the ceiling is warmer than the air near the floor? Or that water in a pool is cooler at the deep end?

PowerPoint Presentation:

Convection currents cause the cooler breezes you experience by a large body of water. These currents also cause the movement of magma within the earth.

RADIATION:

RADIATION Radiation is the transfer of energy by electromagnetic waves Radiation does NOT require matter to transfer thermal energy Radiation = Radiates (heat escaping the sun)

Examples of RADIATION:

Examples of RADIATION
