What happens to the vapor pressure of a fumigant as the temperature increases?

As the temperature increases, the vapor pressure of a fumigant increases. This is due to the physical properties of gases and liquids; higher temperatures provide more kinetic energy to the molecules, causing them to move more vigorously. As a result, more molecules enter the vapor phase, which directly elevates the vapor pressure.

Fumigants often work effectively at higher temperatures because an increased vapor pressure can lead to better penetration and distribution of the fumigant within the area being treated. Understanding this relationship between temperature and vapor pressure is crucial for ensuring the effectiveness and safety of fumigation processes.
