78Groundwater flow equation — Used in hydrogeology, the groundwater flow equation is the mathematical relationship which is used to describe the flow of groundwater through an aquifer. The transient flow of groundwater is described by a form of the diffusion equation, similar …
79Smoulder — Smouldering (or smoldering in American spelling) is a flameless form of combustion, deriving its heat from oxidations occurring on the surface of a solid fuel. Common examples are the initiation of fires on upholstered furniture by weak heat… …
80Classical and quantum conductivity — Classical and quantum mechanical views of conductivity have both described the movements of electrons in a metallic solid. The free electron gas that is present in metallic solids is the reason for an important property of all metals:… …
