WebThe transfer of heat can occur in three ways: conduction, convection, and radiation. Heat transfer occurs between states of matter whenever a temperature difference exists and heat transfer occurs only in the direction of decreasing temperature, meaning from a hot object to a cold object. WebApr 7, 2024 · Heat transfer by convection either occurs due to thermal diffusion (motion of fluid molecule) or advection, in which heat is transferred by the bulk motion of heat currents in the fluid. Newton's Law of Cooling Under normal conditions, the heat transfer due to convection is directly proportional to the temperature difference between the parts.
