Mass conduction

WebAn example is the conduction of heat along the handle of a spoon in a cup of hot coffee. The process of heat transfer in soil is primarily one of conduction, although some mass movement of gases or water may occur. The process of heat transfer between an organism and a fluid is a combination of conduction and mass movement. http://weewave.mer.utexas.edu/MED_files/Former_Students/thesis_dssrtns/Hartin_O_diss/ch3.pdf
