Temperature, Thermal Energy, and Heat
Thermal Energy
What is it?
Temperature
The measure of the average kinetic energy of the particles of a substance.
Total kinetic energy of all the particles in an object
In other words... It's heat!!
Kinetic energy is the energy of movement!
Remember!
The more atoms move around, the more heat energy the object has

Convection
Conduction
Thermal energy is transferred in ways:
Radiation is energy that is transported by waves traveling through space.
An example of radiation is the warmth that you feel coming from the sun. The energy from the sun travels through space as a wave in the form of sunlight
Conduction
Conduction is heat that is transferred from one substance to another through direct contact.
You may have felt conduction if you've ever touched a pan and burned your finger!
An object that easily conducts heat, is called a conductor. Solids, especially metals, are the best conductors of heat.
This is why you use pot holders when touching metal pans coming out of a hot oven!
This is the transfer of thermal energy through movement of a liquid or gas.
Convection
It is driven by differences in density. Warmer water or air is more dense than colder water or air. So the warmer materials rise and the cooler materials sink. This rising and sinking motion forms a circular pattern called convection currents.
