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 World of Chemistry The World of Chemistry The World of Chemistry is a television series on introductory chemistry hosted by Nobel prize-winning chemist Roald Hoffmann. The series consists of 26 half-hour video programs, along with coordinated books, which explore various topics in chemistry through experiments conducted by Stevens Point emeritus professor Don Showalter the "series demonstrator" and interviews with working chemists, it also includes physics and earth science related components. The series was produced by the University of Maryland, College Park and the Educational Film Center and was funded by the Annenberg/CPB Project (now the Annenberg Foundation), it was filmed in 1988 and
