API gravity describes which of the following?

API gravity describes which of the following?

• A. Weight Of Fuel Compared To The Weight Of Water
• B. Vapor Pressure Relative To Water
• C. Boiling Point Relative To Water
• D. Color Relative To Water

Answer: (A)

API gravity is a measure of how heavy or light a petroleum liquid is compared with water. It’s essentially a density comparison: liquids with higher API gravity are lighter than water, while liquids with lower API gravity are heavier. For context, a liquid with the same density as water has an API gravity of 10. This makes the statement describing the weight of the fuel relative to water the correct description. Vapor pressure, boiling point, and color are governed by other properties and are not what API gravity quantifies.
