What characteristic helps to identify whether a substance will float or sink in water?

• A. pH level
• B. Specific gravity
• C. Boiling point
• D. Density

Answer: (B)

The characteristic that helps to identify whether a substance will float or sink in water is specific gravity. Specific gravity is a measure that compares the density of a substance to the density of water. Since water has a specific gravity of 1, if a substance has a specific gravity less than 1, it will float; if it has a specific gravity greater than 1, it will sink. This relationship is crucial in various applications, particularly in hazardous material handling, as it assists in predicting the behavior of substances when they come into contact with water. Understanding specific gravity allows responders to determine the appropriate actions in a spill or containment situation, making it an essential concept in hazardous materials management.
