What can occur if a fumigant like methyl bromide is subjected to lower temperature conditions?

1. It evaporates quickly

2. It remains unchanged

3. It may condense

4. It becomes a solid

The correct answer is: It may condense

When a fumigant like methyl bromide is subjected to lower temperature conditions, it may condense. This is because gases tend to decrease in pressure and volume as temperatures drop, leading to condensation. Methyl bromide, like many other fumigants, transitions from a gaseous state to a liquid state under cooler temperatures. This is a crucial consideration during fumigation processes, as the effectiveness and behavior of the fumigant can change based on temperature, impacting the overall efficacy of pest control. Understanding this behavior helps fumigation professionals adjust their methods accordingly to ensure that the fumigant remains effective throughout its application.
