In the illustration, concepts of heat are CONDUCTION, CONVECTION, and RADIATION. Heat is an energy that is moved or transferred from one object to another. Heat usually moves from one high-temperature object to a low-temperature object. An example is when you put a spoon in boiling water, the spoon becomes hot.
Heat Transfer
Heat may only be transferred in three ways:
Conduction. Conduction is the process where heat is transferred to another object. An example is when the handle of the pot becomes hot. This is because the body of the pot, as it is heated, transfers the heat to conductible things that it comes in contact with.
Convection. Convection is the process where heat is transferred causing the movement of the molecules away from one another. An example is when the water boils and forms bubbles on the surface. This is because water molecules with heat push up to the surface above other cooler water molecules within the pot.
Radiation. Radiation is the process where heat is transferred as it is produced and moves in all directions into space. An example is when the surrounding is heated due to the heat of the fire. This is because the fire emits heat-producing radiation that spreads reaching people near the fire.
