all three types of heat transfer; Conduction, Convection and Radiation labels showing each type of heat transfer a one- to two-sentence description for each example explaining how the heat is being transferred. Do not simply define conduction, convection, and radiation. Your description of conduction, convection, and radiation should be specific to your illustration and in your own words.

conduction is the process by which heat or electricity is directly transmitted.
convection is the movement caused within a fluid by the tendency of hotter and therefore less dense.
radiation is the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.

Conduction is when two solid or liquid bodies are in contact.... like u can take two balls ...one much hotter than the other... if u put them together.. after some time.. they both will have the same temperature....

Now convection usually happens in air and liquids.. when air is heated.. the warmer part being lighter moves up... and the colder part remains down... this heated air when moves upwards is known as convection... like for example: if u boil water... the heated water molecules rise up and the colder ones go down.. gain the colder ones get heated come up and the others go down .. it is like a cycle... here too.. the heated molecules of water in contact with air.. makes the air warmer... due to which the water molecules lose heat... and this warm air moves up and gradually this cycle goes on until water becomes water vapour....

now radiation... IT DOES NOT NEED ANY MEDIUM like the other two... for example: heat from the sun reaches the earth atmosphere.. how? there is no medium between sun and earth ...radiation takes place.. okay? now.. the heat on travelling through earth's atmosphere carries out conduction due to which the heat reaches us.. after all this... finally when heat reflects back into atmosphere... convection takes place... where the heated molecules move up into the atmospheric layers....
