What is the correct term for the change of phase from a liquid to a vapor?

• A. Boiling
• B. Evaporation
• C. Boiling point
• D. Vaporization

Answer: (B)

The change of phase from a liquid to a vapor is referred to as vaporization, which encompasses both boiling and evaporation. The term "vaporization" is a broader classification that includes all processes where a liquid transitions into a vapor phase. Boiling is a specific type of vaporization that occurs at a particular temperature known as the boiling point, where the liquid forms vapor bubbles within its bulk. Evaporation, on the other hand, refers to the process by which molecules at the surface of a liquid gain enough energy to enter the vapor phase, often occurring at temperatures below the boiling point. Although the answer selected indicates evaporation specifically, the most accurate and comprehensive term covering the transition from liquid to vapor is vaporization. In contrast, boiling point is a defined temperature where boiling occurs, rather than a phase change itself. Therefore, the best understanding involves recognizing that while "evaporation" captures a specific scenario, vaporization effectively describes the overall change of phase from a liquid to a vapor.
