Conduction is a familiar process. An example of conduction is when you place a pan on an electric stove. The stove element causes the pan to heat up. On the microscopic level, the atoms in the burner move faster, and they run into the atoms in the pan, causing them to move faster. Conduction will not be important in main-sequence stars , simply because the atoms are not close enough together.
Radiation is the process of transferring energy using photons.
Another example is a black dog in the sun the dog s coat will warm up, because it is absorbing photons from the sun. Radiation is an important process in main-sequence stars . Convection is the process of transferring energy by motion. We previously discussed convection with respect to granulation on the surface of the sun. It is similar to boiling of water on the stove.
