1. Judging  from its unit W/m.K can we define thermal conductivity of a  material as the rate of heat transfer through the material per unit thickness per unit temperature difference? Explain. 2.How does heat conduction differ from convection? 3. Does any of the energy of the sun reascht the earth by conduction or convection?
