Thermal energy
Heat transfer by radiation
Alpha
Because no particles are used in radiation it can also happen through space(vacum)
Beta
Gama
Infra-red
Radio-waves
microwaves
Optical light
X-ray
Ultraviolet
Metals are good conductors
Non-metals and glass are poor conductors
It is conducted from the hot end to cold end
The electrons in an atom allow the heat to be transferred quickly to anywhere in the metal
They then leave behind positive charged ions
The more heat, the more kinetic energy
Convection
Only liquids and gases can do that
when the liquid is heated up it becomes less dense
So it rises up
Then as it cools down it becomes less dense
This forms a convection current
Fluids are liquids and gases
Heat is basically thermal energy.
It can be conducted from one place to another
