Conduction, Convection, Radiation
An example of convection is when you boil the kettle and the heat from the heat pot boils the water at the bottom and the goes to the top of the kettle.
Radiation is the transfer of heat from one place to another using invisible waves. All objects give out heat via radiation but hot objects radiate more heat than cool objects. Dark objects radiate more heat than light objects.
An example of radiation in everyday life is when you touch a dark colored car after it has been sitting in the sun for a while.
