Convection is the transfer of energy in a moving medium, most often a liquid or gas flowing through a duct or over an object. The transfer of energy in a flowing fluid is not only due to conduction (i.e., the interactions between micro-scale energy carriers) but also due to the enthalpy carried by the macro-scale by: 2.

Chapter Summary-Modes of Mass Transfer • Molecular Diffusion 1. It is the movement of mass from a higher to a lower concentration due to random molecular motion. It is described by Fick's law (Eqn. ) which states that the flux of a mass species is proportional to the concentration gradient of that species.
