Capable of wasting away, or of easily passing into the aëriform state; subject to evaporation.

Fig.: Light-hearted; easily affected by circumstances; airy; lively; hence, changeable; fickle; as, a volatile temper.

readily evaporate

Description of any substance that evaporates easily.

Refers to memory that is not saved when power is lost or turned off. See also nonvolatile.

Susceptible to loss; a way of saying that all the data disappears forever if the power fails.

Descriptive of a data storage device that loses its contents when power is lost (turned off).

Subject to change. Used to refer to electronic memory which loses its contents when its power source is removed.

wine that tastes slightly vinegary because it has a high level of acetic acid. This is also referred to as volatile acidity.

A wine spoiled by the presence of acetic acid is said to be volatile, or to have volatile acidity. It is acceptable as a by-product of alcoholic fermentation but only up to a level of 600-800ppm.

refers to wines that taste slightly vinegary because of high levels of acetic acid; also referred to as volatile acidity.

all wines have volatile acidity, but a volatile wine is on its way to vinegar

likely to change rapidly and often.

Describes a market with large price fluctuations in either or both directions.

Tending to rapid and extreme fluctuations.

Situation that changes rapidly or suffers from extreme fluctuations

Insures that, when accessing a variable with multiple threads, any cached copies of that variable in a separately-executing thread are updated with the original instance.

The quality of a value that changes unexpectedly. The compiler cannot trust that the value of a volatile variable remains constant over time, and therefore cannot perform certain optimizations. Declared explicitly by the programmer, or determined by the compiler.

a seldom-used keyword in C which has implementation-defined semantics but is usually taken to mean that a variable should not be placed in a register as it may be subject to side effects from hardware or signal handlers.

A Java keyword used in variable declarations that specifies that the variable is modified asynchronously by concurrently running threads.

Amount of solvent or liquid components in a coating.

Passing from a liquid into a gaseous state.

The solvent portion of a coating.

Clause is Volatile if its constituent Propositions change frequently. As with register variables in C, the Truth Maintenance System may, if given a hint about a Clause's volatility, be able to represent it more efficiently.

Oil Plant constituent which has many beneficial effects on the body. It can also be distilled to produce essential oil

Predicate property. The clauses of a volatile predicate are not saved in saved-states.
