What is another key physical characteristic influencing a fumigant's change from liquid or solid to gas?

The boiling point is a critical physical characteristic that influences how a fumigant transitions from a liquid or solid state to a gaseous form. The boiling point is the temperature at which a substance changes from a liquid to a gas. For fumigation purposes, understanding the boiling point of a fumigant is essential because it determines how the material can be applied effectively and under what conditions it can vaporize to penetrate the target area.

When a fumigant is heated to its boiling point, it will evaporate and form gas, which is crucial for its effectiveness in pest control. This transformation allows the fumigant to disperse throughout the area being treated, ensuring adequate exposure to the target organisms. Knowledge about the boiling point helps fumigators plan their application processes and ensures they can achieve the desired concentration of the fumigant in the air.

While melting point and specific gravity can provide useful information about the physical state and density of a fumigant, they are not directly responsible for the transition from liquid or solid to gas. Color, although it may be relevant for safety and identification purposes, does not influence the phase change of a fumigant in any significant way.
