Appendix. By radiation, heat is transmitted optically through a transparent medium or space. Convective heat is transferred between a convecting fluid and a solid or other fluid. Conduction within a solid, liquid , or gas is the principal mode of heat transfer in the earth and is the principal thermal property considered herein. Summary
