☆CONVECTION:

▪︎ The movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.

▪︎ It is the final transfer of energy by surface.

RADIATION:

▪︎ The emission of energy as electromagnetic wave or as moving subatomic particles, especially high-energy particles which cause ionization.
