Define volatile.
A
Substances that contain particles that evaporate or become gaseous quickly
B
A type of computer memory that is very fast but also very expensive
C
A stock market term that describes stocks that are highly unpredictable
D
A type of computer file that can be easily changed or altered
Explanation: 

Detailed explanation-1: -A volatile substance is one that evaporates or sublimates at room temperature or below. Volatile substances have higher vapor pressures versus non-volatile substances at the same temperature.

Detailed explanation-2: -Volatile substance use may be defined as the deliberate inhalation of volatile compounds to produce psychoactive effects. These compounds have few characteristics in common, other than their intoxication effects and the behavioural effects they produce.

Detailed explanation-3: -A highly volatile substance such as rubbing alcohol (isopropyl alcohol) will quickly evaporate, while a substance with low volatility such as vegetable oil will remain condensed. In general, solids are much less volatile than liquids, but there are some exceptions.

Detailed explanation-4: -Volatility describes how easily a substance will vaporize (turn into a gas or vapor). A volatile substance can be defined as (1) a substance that evaporates readily at normal temperatures and/or (2) one that has a measurable vapor pressure. The term volatile usually applies to liquids.

Detailed explanation-5: -Volatile substances: Volatile substances have the capability to go into the vapor phase. This may happen during heating or without heating. Volatility and the vapor pressure of a substance are related. If the volatility is high, the vapor pressure is also high. If the volatility is low, then the vapor pressure is low.
