Materials with low boiling points are classified as?

• A. Volatile
• B. Nonvolatile
• C. Dense
• D. Corrosive

Answer: (A)

Volatility is the tendency of a substance to vaporize. A low boiling point means the substance reaches the temperature where its vapor pressure equals the surrounding pressure at a relatively small amount of heat, so it readily forms vapor. That makes it volatile. Nonvolatile substances have high boiling points and don’t vaporize easily, while density describes mass per volume and corrosive describes reactivity with materials—neither governs how readily a substance becomes vapor.
