Convection Convection is the transfer of heat by the circulation of currents from a hotter to cooler region. Convection currents only occur in liquids and gases because it involves movement of fluid particles. Convection is used in our daily lives as well as for natural things.
Convection Convection involves two processes: Diffusion and Advection Diffusion is the random motion of the individual particles in the fluid. Advection is the transportation of heat by the large- scale motion of currents in the fluid. AdvectionDiffusion
