What is the density of gasoline?
2 Answers
Gasoline density ranges from 0.70g/cm³ to 0.78g/cm³. Below is an introduction to the physicochemical properties and uses of gasoline: Physicochemical properties of gasoline: At room temperature, gasoline appears as a colorless to light yellow, easily flowing liquid. It is difficult to dissolve in water, highly flammable, with a distillation range between 30°C to 205°C. It becomes explosive when its concentration in air reaches 74-123 grams per cubic meter and encounters fire. The calorific value of gasoline is approximately 44,000 kJ/kg. Main uses of gasoline: Gasoline is one of the most widely used light petroleum products and serves as an important fuel for engines. Based on the manufacturing process, gasoline components can be classified into straight-run gasoline, thermal cracking gasoline (coking gasoline), catalytic cracking gasoline, catalytic reforming gasoline, polymerization gasoline, hydrocracking gasoline, alkylation gasoline, and synthetic gasoline, among others.
I find the topic of gasoline density quite interesting, as I often drive for business trips. Gasoline density fluctuates between 0.72 and 0.78 grams per cubic centimeter, depending on weather and fuel type. For example, in hot summer months, the density decreases - the fuel gauge may show less volume when refueling, but the weight could remain the same. I remember once refueling with 92-octane gasoline (density ~0.73) and noticing more stable fuel consumption, whereas 95-octane (density 0.75) made the car run smoother when full. Higher density means more energy per liter, potentially saving money long-term, though the actual impact is negligible. While driving, there's no need to focus on density, but understanding it can help avoid poor-quality gas stations and prevent minor engine issues. Regular oil changes and maintenance are what truly matter - density values are just reference points.
