Question 95Safety & Environmental - 1st Asst/Chief

The correct answer is C) specific gravity. The specific gravity of a liquid is the term used on a Material Safety Data Sheet (MSDS) to describe whether the liquid is lighter or heavier than water. Specific gravity is a measure of the density of the liquid compared to the density of water, which has a specific gravity of 1. Liquids with a specific gravity less than 1 are lighter than water and will float, while liquids with a specific gravity greater than 1 are heavier than water and will sink. The other answer choices are incorrect because they do not directly describe whether a liquid is lighter or heavier than water. Solubility refers to how well a substance dissolves in water, flotation point is not a standard MSDS term, and viscosity measures the resistance of a liquid to flow.
