Answer:
The appropriate answer is D " volatility."
Step-by-step explanation:
Volatility refers to the susceptibility of liquids to vaporize. Perfume is liquid when applied but because of volatility, it has a tendency to vaporize and so it will convert to a gas and diffuse across the room. The process by which a liquid changes to a vapor is called evaporation. Volatility describes how easily a substance will vaporize (turn into a gas or vapor). A volatile substance can be defined as a substance that evaporates readily at normal temperatures and/or one that has a measurable vapor pressure. The term volatile usually applies to liquids.
