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. What two kinds of heat transfer are represented?

• Stove → Pot = radiation, Pot → Egg = conduction

• Stove → Pot = conduction, Pot → Egg = radiation

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

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