Well known for Designing, Manufacturing, Supplying and Commissioning of . Molecules are always moving. Molecules move randomly and bump into each other and other barriers. Concentration gradient. Concentration Gradient - change in the concentration of a substance from one area to another.. Heating media or device.. Used for heating and melting.. For . providing heat to chemical reactions for processes like . cracking.. The furnace may be heated by fuel as in many furnaces coke is used as a fuel.. CAPACITY - 2 X 15 TONNES.      . AN INDUCTION FURNACE USES A COMBINATION OF ELECTRICAL RESISTANCE AND HYSTERESIS LOSSES TO HEAT METAL. .. THE FURNACE HEATS THE METAL BY EXPOSING IT TO THE MAGNETIC FIELD AROUND A COIL-CARRYING ALTERNATING CURRENT. . Lessons from the Furnace:. Key Terms.

Diffusion is the movement of molecules or particles from a region of high concentration to a region of low concentration. . . Diffusion is a process of . mass transport. that involves the atomic . or molecular motion. .. In the simplest form, the diffusion can be defined as the . random walk. of an ensemble of particles from regions of high concentration to regions of lower concentration.
