What term is used to describe gases that are normally liquids or solids?

• A. Fumes.
• B. Mists.
• C. Aerosols.
• D. Vapors.

Answer: (D)

The term that describes gases that are normally found as liquids or solids is vapors. Vapors refer to the gaseous state of a substance that typically exists in liquid or solid form at room temperature. When a substance transitions from its liquid or solid state into the gas phase, it forms vapor. This process occurs at temperatures below the boiling point of the liquid, allowing the substance to exist as a gas in a mixture with the ambient air. In contrast, the other terms have specific meanings. Fumes are generally fine solid particles that are dispersed in the air, often produced from processes like combustion or chemical reactions. Mists refer to tiny liquid droplets suspended in the air. Aerosols consist of a mixture of small particles and liquid droplets dispersed in gas but typically include a broader range of substances compared to vapors.
