Volatile means something changing or changeable. It can refer to:

In general:

• Volatility, a measure of instability

In economics:

• Volatility (finance), a measure of the risk in a financial instrument

In chemistry:

• Volatility (chemistry), a measure of the tendency of a substance to vaporize. Volatility most frequently refers to the Standard deviation of the continuously compounded returns of a Financial instrument with a specific time horizon Volatility in the context of Chemistry, Physics and Thermodynamics is a measure of the tendency of a substance to Vaporize. It has also been defined as a measure of how readily a substance vaporizes.
• Volatiles, a group of compounds with low boiling points that are associated with a planet's or moon's crust and/or atmosphere
• Volatile liquids, liquid with a high vapor pressure or low boiling point
• Volatile organic compounds, organic compounds that can evaporate at normal temperature and pressure, and are often regulated by governments
• Volatile anaesthetics, a class of anaesthetics which evaporate easily
• Volatile substance abuse, the abuse of household inhalants containing volatile compounds
• Volatile oil, also known as essential oil, an oil derived from plants with aromatic compounds used in cosmetics and flavoring
• Volatile acidity, a term used in winemaking to indicate an unacceptably high level of acid or vinegar and baking soda. In Planetary science, volatiles, are that group of elements and compounds with low boiling points (see volatile) that are associated with a planet's or moon's This article describes a highly specialized aspect of its subject in the "Terminology and legal definitions" section The volatile anaesthetics are a class of General anaesthetic drugs An essential oil is a concentrated Hydrophobic Liquid containing volatile Aroma compounds from Plants They are also known as volatile A wine fault or defect is an unpleasant characteristic of a Wine often resulting from poor Winemaking practices

In computer science:

• Volatile variables, variables that can be changed by an external process
• Volatile memory, memory that lasts only while the power is on (and thus would be lost after a restart)
