Which has a greater density, gasoline or water?

[Tyrone]

Compared to gasoline, water has a greater density. The density of water is approximately 1000 kg/m³, while the density of gasoline is about 800 kg/m³. The density of gasoline can also vary due to seasonal factors. Below are detailed explanations: 1. Gasoline Density: Different grades of gasoline have varying densities. The most common are 92-octane and 95-octane gasoline. The density of 92-octane gasoline is approximately 0.72 g/ml, while 95-octane gasoline has a density of about 0.725 g/ml, and 98-octane gasoline has a density of around 0.737 g/ml. From this, it can be observed that the higher the gasoline grade, the greater its density. This is mainly because gasoline is a mixture, and different grades are formulated by adding various additives to base gasoline. 2. Gasoline Grades: The reason gasoline has different grades is primarily due to varying anti-knock properties. Higher-grade gasoline does not necessarily mean fewer impurities but rather better anti-knock performance. The higher the gasoline grade, the less likely the engine is to experience premature combustion during operation. Additionally, the compression ratio of the engine determines the gasoline grade required.
