Heat Transfer

Heat energy flows away from hotter objects to cooler surroundings.

Heat is transferred in 3 different ways:

·         Convection

·         Radiation

·         Conduction

·         Convection and conduction involve the transfer of energy by particles.

·         Infrared radiation (thermal) is the transfer of heat energy by electromagnetic waves.

·         Conduction is the main form of heat transfer in solids.

·         Convection is the main form of heat transfer in liquids and gases.

·         Emission of thermal radiation occurs in solids, liquids and gases.

·         Any object can both absorb and emit heat radiation, whether conduction or convection are taking place or not.

·         The bigger the temperature difference, the faster the heat is transferred between…
