What process describes the change of a liquid into a gas?

• A. Vaporization
• B. Condensation
• C. Sublimation
• D. Deposition

Answer: (A)

Vaporization is the process by which a liquid transforms into a gas. This process can occur through evaporation, where the liquid gradually changes to vapor at temperatures below its boiling point, or through boiling, which occurs at the boiling point where bubbles form within the liquid. Understanding vaporization is crucial in hazardous materials scenarios, as it can affect how substances behave in various environmental conditions and impact containment and response strategies. The other processes listed are different states of matter transitions; for example, condensation refers to the change of gas to liquid, sublimation is the transition from solid to gas directly, and deposition is the change from gas to solid.
