Transcript of Conduction, Convection, and Radiation

Thermal Energy: a Review
Conduction, Convection, and Radiation
CONDUCTION
A heat transfer that happens because molecules are physically touching.
CONVECTION
A heat transfer within a liquid or gas where the warm part rises and the cool part sinks.
Warm molecules move faster,
meaning they can
spread out more, making them less dense, causing them to rise.
Radiation
A heat transfer from the energy of electromagnetic waves.
Three Ways
Heat can be transferred in three ways:
All atoms are moving.
When atoms move, they produce friction which we feel as heat.

The faster they move, the higher the temperature will be.

The movement of these molecules, can be transferred to other molecules.
In other words, warm objects can give their heat to cooler objects.
We call that a heat transfer.
CONDUCTION
CONVECTION
RADIATION
This can happen
between two objects,
but is also
how heat is transferred within one object.
Cool molecules move slower,
meaning they
do not move away from each other very much, making them more dense, causing them to sink.
Convection
