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.

Institute of Chemistry of Ireland Chemistry of Ireland on 18 January 1950. Members of the ICI are chemists who satisfy certain qualification criteria. There are several membership categories. The official journal of the ICI is "Irish Chemical News". Two issues are published each year and are available through the institute website. The "journal Physical Chemistry Chemical Physics" (PCCP) published by the Royal Society of Chemistry is co-owned by the ICI along with 17 other national chemical societies. The journal publishes a broad range of research articles in physical chemistry, chemical physics and biophysics. Institute of Chemistry of Ireland The Institute of Chemistry of Ireland (ICI)
