What is volatility?

What is volatility?

• A. Dissolves in water
• B. Turns into vapor
• C. Binds to soil
• D. Turns into a solid

Answer: (B)

Volatility describes how readily a chemical becomes a gas. In practical terms, a volatile pesticide easily vaporizes at normal temperatures, turning into a vapor that can drift through the air. That’s why the correct description is “turns into a vapor”—it captures the idea of vaporization and gas-phase movement. This matters in pest management because high volatility means more potential for off-target drift and inhalation exposure, influencing handling, application conditions, and safety measures. The other options describe different properties: dissolving in water is about solubility, binding to soil is about adsorption to the soil, and turning into a solid describes deposition or crystallization.
