THE MOLE A mole (symbol Mol) is the base unit of quantity of a substance in the metric system. A mole is the quantity of a substance that contains 6.02 x 1023 units. A "unit" is the smallest measurable entity in the substance‚ generally either an atom or a molecule. The number of units in a mole was determined by Italian chemist (a scientist specializing in the composition‚ structure‚ properties‚ and reactions of matter) Amedeo Avogadro (1776-1856)‚ one of the founders of modern physical chemistry

UNSTEADY STATE HEAT TRANSFER Heat transfer processes are prominent in engineering due to several applications in industry and environment. Heat transfer is central to the performance of propulsion systems‚ design of conventional space and water heating systems‚ cooling of electronic equipment‚ and many manufacturing processes (Campos 3). Unsteady state conduction is the class of heat transfer in which the temperature of the conducting medium varies with time and position. This occurs frequently in
