Volatility (chemistry) Volatility (chemistry) In chemistry and physics, volatility is quantified by the tendency of a substance to vaporize. Volatility is directly related to a substance's vapor pressure. At a given temperature, a substance with higher vapor pressure vaporizes more readily than a substance with a lower vapor pressure. The term is primarily written to be applied to liquids; however, it may be used to describe the process of sublimation which is associated with solid substances, such as dry ice (solid carbon dioxide) and osmium tetroxide (OsO), which can change directly from the solid state to a vapor, without becoming liquid. The
Semenov Institute of Chemical Physics The Institute's aim has been defined as "the implementation of physical theories and methods into chemistry, chemical industry and some other branches of national economy". Its main areas of scientific inquiry are the kinetics and mechanism of chemical reactions, catalysis of chemical reactions, theory and dynamics of elementary processes, physics and chemistry of solids, structure and properties of polymers and composites, fundamentals of polymerization processes, physics and chemistry of combustion, shock waves and detonation. In 1956, a branch of the Institute of Chemical Physics was established in Chernogolovka; this was reorganized in 1997 as the independent Institute of Problems of
