Equilibrium fractionation — Equilibrium isotope fractionation is the partial separation of isotopes between two or more substances in chemical equilibrium. Equilibrium fractionation is strongest at low temperatures, and (along with kinetic isotope effects) forms the basis… … Wikipedia
Mass-independent fractionation — Mass independent (isotope) fractionation refers to any chemical or physical process that acts to separate isotopes, where the amount of separation does not scale in proportion with the difference in the masses of the isotopes. Most isotopic… … Wikipedia
Mass balance — A mass balance (also called a material balance) is an application of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown,… … Wikipedia
Mass-action ratio — The mass action ratio[1], often denoted by Γ, is the ratio of product concentrations to reactant concentrations. If the product and reactant concentrations are at equilibrium then the mass action ratio will equal the equilibrium constant. At… … Wikipedia

Mass fraction (chemistry) — In chemistry, the mass fraction wi is the fraction of one substance with mass mi to the mass of the total mixture mtot, defined as [1]: The sum of all the mass fractions is equal to 1: It is one way of expressing t … Wikipedia
Mass flow sensor — A mass airflow sensor. A mass air flow sensor is used to find out the mass flowrate of air entering a fuel injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the… … Wikipedia
