Which change of state corresponds to a liquid turning into a solid?

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

Answer: (C)

The transition from a liquid to a solid is known as freezing. This process occurs when the temperature of a liquid drops to its freezing point, causing the molecules within to slow down and arrange themselves into a more fixed and structured formation typical of solids. During freezing, energy is released from the liquid, which allows the molecules to bond more tightly, resulting in a solid-state. Understanding this phase change is important in hazardous materials training, as certain liquids can freeze at specific temperatures that may significantly affect their handling, storage, and overall hazard potential. The surrounding environmental conditions, such as temperature, play a critical role in this transformation and can help emergency responders predict the behavior of hazardous substances they may encounter.
