The process by which heat diffuses through a solid or a stationary fluid is termed heat conduction. Situations in which heat transfer from a wetted surface is assisted by the motion of the fluid give rise to heat convection and when the fluid undergoes a liquid-solid or liquid-vapor state transformation at or very near the wetted
