Which term is described as volatile organic compounds that readily vaporize at typical atmospheric conditions?

• A. Greenhouse Gases
• B. Hazardous Air Pollutants
• C. Volatile Organic Compounds (VOCs)
• D. Particulate Matter

Answer: (B)

Volatile Organic Compounds are organic compounds that readily vaporize at typical atmospheric conditions because they have high vapor pressures and low boiling points. This means they exist as gases in the air at room temperature, which is why they can participate in atmospheric reactions and contribute to air pollution. Hazardous Air Pollutants is a regulatory category that includes various harmful substances, some of which are VOCs, but the description given—the compounds that vaporize easily in the atmosphere—points to VOCs specifically. Greenhouse gases trap heat rather than being defined by volatility, and particulate matter consists of solid or liquid particles, not gas-phase compounds. So the term that fits the description is Volatile Organic Compounds (VOCs).
