What is the specific gravity of water relative to standard?

• A. 1.0
• B. 0.0
• C. 0.5
• D. 1.5

Answer: (A)

Specific gravity is a way to compare a liquid’s density to the density of water using water as the reference. By definition, water itself serves as the baseline, so its specific gravity is 1.0. This is based on water having a density of 1.0 g/cm^3 at the standard reference temperature (around 4°C). Other liquids will have values above or below 1.0 depending on whether they are denser or less dense than water. The given options include values that don’t describe water itself, so the correct answer is 1.0.
