<P> Convection can not take place in most solids because neither bulk current flows nor significant diffusion of matter can take place . Diffusion of heat takes place in rigid solids , but that is called heat conduction . Convection , however , can take place in soft solids or mixtures where solid particles can move past each other . </P>
