What is the difference between Conduction, Convection, Radiation and Evaporation!?
Conduction is heat transfer between part of the same material or different material which are adjacent to one another. Convection is heat transfer from one material to another via a medium, such as air or water. Radiation is heat transfer without any medium and through electromagnetic waves, such as between the Sun and the Earth. Evaporation is heat absorption by liquids which then becomes a gas, such as when you boil water or simply leave a cup of water around and it is evaporated after a while.
