When an egg is boiled in a pot of water on the stove, there is more than one kind of heat transfer. Heat is transferred from the stove to the pot directly since they are physically touching. Heat is also transferred from the pot to the egg, carried through the water.

Stove → Pot = conduction, Pot → Egg = convection.

Explanation:

There are three ways in which heat is being transferred from one medium to the other and the means are; radiation, conduction and convection heat transfer.

Radiation is the process in which heat is being transferred through emission in form of electromagnetism. Conduction heat transfer Is the process in which heat is being transferred through contact that is two bodies touching each other. Convection heat transfer is the kind of heat that happens through gases.

Since the heat from the stove touching the pot is the conduction heat transfer.

After the water has been heated up, the gas from the water makes the convection heat transfer.
