  • heat is transferred in three different ways
    • heat radiation can be transferred by radiation, conduction or convection.
    • heat radiation is the transfer of heat energy by infrared radiation
    • Conduction and convection involve the transfer of energy by particles.
    • Conduction is the main form of heat transfer in solids.
    • convection is the main form of heat transfer in liquids and gases.
    • Infrared radiation can be emitted by solids, liquids and gases.
    • Any object can both absorb and emit infrared radiation, whether or not conduction or convection are also taking place.
    • The bigger the temperature difference between a body and its surroundings, the faster energy is transferred by heating.
