At what temperature do VOCs such as formaldehyde evaporate?

• A. High temperatures only
• B. Low temperatures
• C. Room temperature
• D. Requires boiling temperatures

Answer: (C)

VOCs like formaldehyde readily escape into the air at typical indoor conditions because they have measurable vapor pressure even without heating. In other words, room temperature is enough for them to evaporate from surfaces or products into the surrounding air. Warmer conditions can speed up the process, but they don’t need boiling temperatures to release into the air. So the best description is that they evaporate at room temperature.
