It is the temperature difference between the two neighboring objects that causes this heat transfer The heat transfer continues until the two objects
Temperature is a measure of the average kinetic energy of the atoms or molecules of a substance • Heat is the transfer of energy from a substance at a higher
RADIATION – This is the only form of heat transfer that does not require contact between substances No contact is required because the energy is
Conduction is the transfer of energy from the more energetic particles of a substance to the adjacent less energetic ones as result of interactions between the
It makes a substance hotter Conduction 2 Convection and 3 Radiation In solids, heat passes from one point to another through conduction
movement of heat between two materials that are touching convection Ask students why they might want to know the thermal conductivity of a substance
Temperature difference between the source of heat and the receiver of heat is The radiant energy transferred between two surfaces depends upon their
heat is usually transferred by convection, in which the motion of the gas or rather is a transfer of energy within a substance (or between substances in
