What is the term for when a pesticide turns into a gas?

Explanation:
Volatilization is the process by which a pesticide moves from a liquid or solid form into a gas. This happens more readily when the chemical has higher vapor pressure and environmental conditions are warm, dry, or windy, or when there is a large exposed surface area. Once volatilized, the pesticide can disperse through the air beyond the target area. Adsorption refers to sticking to soil or surfaces, not turning into gas; persistence is about how long the chemical remains in the environment, and solubility describes how well it dissolves in water, which affects movement in water but not gas formation.
