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.

Nobel Prize in Chemistry the prize is more frequently awarded to non-chemists than to chemists. In the 30 years leading up to 2012, the Nobel Prize in Chemistry was awarded ten times for work classified as biochemistry or molecular biology, and once to a materials scientist. In the ten years leading up to 2012, only four prizes were for work that is strictly in chemistry. Commenting on the scope of the award, "The Economist" explained that the Royal Swedish Academy of Sciences is bound by Nobel's bequest, which specifies awards only in physics, chemistry, literature, medicine, and peace. Biology was in its infancy in
