What is the weight of gasoline?
2 Answers
One liter of gasoline weighs between 700~780g. Here is some relevant information: Gasoline: Gasoline is a volatile, flammable liquid hydrocarbon mixture distilled and cracked from petroleum, used as fuel. It appears as a transparent liquid, is flammable, and has a distillation range of 30°C to 220°C. Principle of thermal expansion and contraction: Thermal expansion and contraction refer to the property of objects expanding when heated and contracting when cooled. This occurs because the movement of particles (atoms) within the object changes with temperature. When the temperature rises, the vibration amplitude of the particles increases, causing the object to expand; however, when the temperature drops, the vibration amplitude of the particles decreases, causing the object to contract.
I often wonder how much gasoline weighs, which depends on its density and temperature. Generally, the density of gasoline is about 0.74 kilograms per liter, meaning one liter of gasoline weighs less than a kilogram. In U.S. units, one gallon of gasoline is roughly 6.2 pounds—it sounds light, but a full tank feels quite heavy. When temperatures are low, gasoline becomes denser and heavier, while in summer it's lighter, so filling up in cold weather might give you a bit more fuel. Gasoline also comes in different types, like regular unleaded and high-octane, with slight variations in density, which can have a minor impact on fuel consumption when calculating a car's total weight. The weight of gasoline affects everyday driving; if I'm going on a long trip, I need to consider changes in fuel tank weight—heavier fuel may slightly increase consumption, but the overall difference is minimal. Next time I fill up, I'll pay attention to the temperature for more precise calculations.
