What is the specific gravity of water?

• A. 0.5
• B. 1
• C. 2
• D. 1.5

Answer: (B)

The specific gravity of water is defined as 1. This is because specific gravity is a comparative measure that indicates the density of a substance relative to the density of water. Since water has a density of approximately 1 gram per cubic centimeter (g/cm³) at standard temperature and pressure, it is used as the baseline for measuring specific gravities of other substances. A specific gravity of 1 means that a substance's density is equal to that of water; if a substance has a specific gravity greater than 1, it is denser than water, and if it is less than 1, it is less dense. Therefore, the answer accurately reflects the standard measure of water's specific gravity.
