What is the key property of a liquid with a specific gravity greater than 1?

A liquid with a specific gravity greater than 1 is denser than water, which has a specific gravity of 1. This density means that if such a liquid is placed in water, it will not be able to displace its weight in water and thus will sink rather than float. Specific gravity is a comparative measure that allows for the identification of whether a substance will float or sink in a fluid, and in this case, higher specific gravity indicates that the liquid will sink. Understanding specific gravity is crucial in hazardous materials handling, as it informs responders about how substances will behave in the presence of water, which is vital for planning containment and mitigation strategies.
