What is the difference in weight between gallon of water and gallon of gasoline?

Answer 1

Equivalent in what way? Gasoline and water are two entirely different chemical compounds. They have dissimilar physical and chemical properties because, well, they are different. Perhaps you are referring specifically to the weight of a gallon of each. If so, then the weight of a gallon of each substance is not equivalent because the gas is less dense than water, so a gallon of water weighs more. When referring to volume, a gallon of gas is equivalent to a gallon of water. Even a gallon of oxygen is equivalent to a gallon of water, in reference to volume. However, when dealing with gases, pressure, temperature, and the number of molecules of the gas must be taken into account.

Answer 2

It depends on how much of each you have! 100 gallons of gasoline weighs more that one gallon of water! I'm not trying to be a wise guy. Your question shows a fundamental misunderstanding of weight and density. Here's a trick question: What weighs more, a pound of rocks or a pound of feathers? The answer, of course, is neither. They both weigh exactly the same, one pound. I suppose what you meant to ask is, "Given equal volumes of water and gasoline, which weighs more?" Then the answer would be, "The denser liquid weighs more because it has greater mass per unit volume." Water weighs (on the surface of the Earth) about 8.3 pounds per gallon. Gasoline, however, is only about 73.7 percent as dense as water, so a gallon of gas (vehicular) weighs only about 6.11 pounds. I say "about" because density varies with temperature, so the weight of a gallon of either liquid will change as its temperature changes.

Answer 3

A gallon of water and a gallon of gasoline have the same volume measure. A gallon, which is a measure of volume, is a gallon, is a gallon. But the gasoline is less dense than water, so it will weigh less. The weight of a gallon of water is about 8.34 pounds , while a gallon of gasoline weighs in the ball park of about 6.25 pounds, depending on the fuel. The gallon of water, which is the same volume as a gallon of gasoline, weighs a bit over 2 pounds more because the water is more dense.

Answer 4

Water (if the same temperature as the gasoline) is more dense than gasoline, making water heavier than gasoline. Actually, quite a bit heavier. Depending on WHICH gasoline, it only weighs 68%-74% of what the same volume of water weighs.

Answer 5

The density (mass/volume) of the oil is less than the density of water. It is the same reason that ice floats on the top of water, rather than sinking. The density of frozen water (ice) is less than the density of liquid water.

Answer 6

It varies slightly depending on the exact formulation and the temperature of the gas, but about 6 pounds.

Answer 7

No, because gasoline has a lower density than water.

Answer 8

water weighs 8 lbs / gal

gas weighs 5 lbs per gal.

Answer 9

Because of greater density
