What term describes the ability of a liquid to convert into vapor?

Volatility is the term that describes the ability of a liquid to convert into vapor. It reflects how readily a substance evaporates and is an important property in various fields, including chemistry and environmental science. A liquid with high volatility will vaporize quickly at a given temperature, while a substance with low volatility will not vaporize as easily.

Viscosity refers to a liquid's resistance to flow; it is a measure of how thick or sticky a liquid is. Density is the mass per unit volume of a substance, indicating how compact its particles are. Fluidity is a more general term that describes the ability of a substance to flow, not necessarily linked solely to the transition from liquid to vapor. Understanding these distinctions helps clarify why volatility is the appropriate term for describing the conversion of liquid to vapor.
