Highly volatile meaning in chemistry
WebDifferences between volatile and non-volatile substances. 1. Volatile substances have a tendency to vaporize whereas nonvolatile substances do not have a tendency to vaporize. 2. Volatile substances have a high vapor pressure at normal room temperature and pressure. Nonvolatile substances do not have a high vapor pressure in these conditions. WebMar 15, 2024 · Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors.
