Mechanisms of heat transfer in paper Heat can transfer through paper thickness by conduction, convection and radiation. Thermal conduction is the diffusion-like transfer of energy. The basic mechanism is the exchange of energy, in gases and liquids, say, in molecular collisions from more energetic particles to less energetic ones by random collisions. In solids, conduction
