VOCs change easily from liquid form to vapor (gas) form.

Explanation:

Organic compounds are chemical materials that must contain carbon and are found in all living creatures. Volatile organic compounds (sometimes referred to as VOCs) are organic compounds that easily become gases or vapors. Along with carbon, they contain some elements such as hydrogen, oxygen, fluorine, chlorine, bromine, sulfur or nitrogen.

VOCs are released from burning fuels, such as gas, firewood, coal, or natural gas. They are also emitted from oil and gas fields and diesel exhausts. They are also released from solvents, paints, glues, and other chemical products that are used and stored at home and at work.

Many VOCs are also hazardous air pollutants. VOCs, when combined with nitrogen oxides, react to form ground-level ozone, or smog, which contributes to global climate change.

Examples of volatile organic compounds are BTEX, gasoline, benzene, formaldehyde, solvents such as toluene and xylene, styrene, and tetrachloroethylene, the main solvent used in dry cleaning.

Many VOCs are commonly used in paint thinners, lacquer thinners, moth repellents, air fresheners, hobby supplies, wood preservatives, aerosol sprays, degreasers, automotive products, and dry cleaning fluids.
