82glacier — glaciered, adj. /glay sheuhr/, n. an extended mass of ice formed from snow falling and accumulating over the years and moving very slowly, either descending from high mountains, as in valley glaciers, or moving outward from centers of… …
83metamorphic rock — Any of a class of rocks that result from the alteration of preexisting rocks in response to changing geological conditions, including variations in temperature, pressure, and mechanical stress. The preexisting rocks may be igneous, sedimentary,… …
84Batch reactor — The Batch reactor is the generic term for a type of vessel widely used in the process industries. Its name is something of a misnomer since vessels of this type are used for a variety of process operations such as solids dissolution, product… …
85Building insulation materials — A selection of insulation materials can aid in building insulation. All of these are based on standard principles of thermal insulation. Materials used to reduce heat transfer by conduction, radiation or convection are employed in varying… …
86ice in lakes and rivers — Introduction a sheet or stretch of ice forming on the surface of lakes and rivers when the temperature drops below freezing (0° C [32° F]). The nature of the ice formations may be as simple as a floating layer that gradually thickens, or it …
87Evaporator — Within a downstream processing system, several stages are used to further isolate and purify the desired product. The overall structure of the process includes pre treatment, solid liquid separation, concentration, and purification and… …
88Thermal conduction — In heat transfer, conduction (or heat conduction) is a mode of transfer of energy within and between bodies of matter, due to a temperature gradient. Conduction means collisional and diffusive transfer of kinetic energy of particles of ponderable …
