What can a specific gravity of less than 1 indicate about a substance?

Explanation:
A specific gravity of less than 1 indicates that a substance is less dense than water. This means that it will float on water, as substances with a lower density will displace an amount of water equal to their volume without fully sinking. Understanding specific gravity is vital in hazardous materials management, as it informs responders during incidents involving spills or leaks about the behavior of substances in water and their potential environmental impacts.
