Three ways to transfer heat.
1-Radeation, 2-Condution, 3-Convection
Radiation heat is heat transfered by eletromagnetic energy.
Conduction is the transfer of heat by by touching two things together.
The two hands are getting heated by touching each other.
Convection is transfering heat by movement.
As the car moves along, the tires get really hot after a long time because the friction from them touching the road and constantly moving
