Heat Transfer
Conduction, Convection and Radiation.
Radiation
Radiation Energy is basically Heat Energy that is transferred by invisible heat waves, like for example, the sun generate heat and light, but the heat of the earth travels here by radiation waves, and we can feel it hit the earth, also there is proof that darker objects can transfer more heat then lighter objects, so a Black car would be losing a lot of heat and the white car would hold on to the heat.
Conduction
Conduction Energy is heat transfer through objects such as metal, when you heat up one end of a metal rod, the heat will make the particles vibrate, making the particles next to them vibrate all the way to the other end, therefore transferring the heat from one end to the other.
