Question 1107 Deck General

The correct answer is A) vaporizes. Upon release to the atmosphere, landfill gas (LFG) readily vaporizes due to its composition, which is primarily methane and carbon dioxide. These gases have low boiling points and easily transition from a liquid or solid state to a gaseous state when exposed to normal atmospheric conditions. The other answer choices are incorrect because LFG does not have corrosive or caustic properties that would cause it to attack materials, and it rises in the atmosphere due to its low density compared to air, not because it attacks anything.
