Which term refers to solid or liquid particles dispersed in a gaseous medium?

Explanation:
Aerosols are suspensions of solid or liquid particles in a gas. This term covers any tiny particles—whether solid like dust or liquid droplets like mist—that are dispersed throughout air. Vapors describe substances that are already in the gas phase, not particles floating in a gas, so they aren’t the right umbrella term. Mists and dusts are specific kinds of aerosols (mists are liquid droplets in air; dusts are solid particles in air), but the broad category that includes both is aerosols.
