THERMODYNAMICS METHODS OF HEAT TRANSFER CONVECTION Liquids and gases are fluids. The particles in fluids can move from place to place. occurs in fluids when the Convection particles with higher kinetic energy move and take the place of particles with less kinetic energy. Thus, energy can be transferred from hotter regions to cooler regions by the movements of molecules over large distances in the fluid. Convection is the transfer of energy from a region of higher temperature to a region of lower temperature due to the motion of the particles of the fluid. Convection above a hot surface occurs because hot air expands, becomes less dense and rises. This known as natural or free convection.
