All the oils that I am aware of have densities lower than the density of water. Hence, a gallon of water will weigh more than a gallon of oil. Oil is less dense than water. Oil of any kind actually floats on water because oil it's chemical makeup. That means that an equal volume of it will weigh less than water. We look at the word "gallon" and think that a gallon of anything is still a gallon. But the question was about weight, not volume! If you took a gallon of water and sat it beside a gallon container of lead, it's obvious the lead would weight more, but both are still a gallon in size. Here are some densities of oils in kg/m3 (water has a density of 1000): Castor oil: 956 Cotton seed oil: 926 California crude oil: 915 Linseed oil: 929 Soybean oil: 926 Whale oil: 925 On a Sidenote: This was the last question posed in the first ever finals of the ABC Television show named Duel with host Mike Greenberg, The Car Salesman lost the chance at 1.8 Million Dollars on his incorrect answer. The weight of a gallon of water is useful to know for fish tank hobbyists. Plain water is usually approximately 8 pounds per gallon.
What else can I help you with?
What is heavier 1 gallon of water or 1 pound of sand?
1 gallon of water is heavier than 1 pound of sand. Water has a density of 8.34 pounds per gallon, so 1 gallon of water weighs more than 1 pound of sand.
What weights more one gallon of water or one gallon of gasoline?
One gallon of water weighs more than one gallon of gasoline. Water has a higher density than gasoline, meaning it is heavier for the same volume.
Will water float on oil?
No, water will sink in oil because oil is less dense than water. This causes the water to be heavier and sink below the oil.
How much does 1 gallon of 15w40 motor oil weigh?
In order to convert from volume to weight, we must know the density. 15w40 has a density of about .879 kilograms per liter. One gallon is about 3.785 liters. Multiplying these two numbers gets us our weight, at approximately 3.327 kilograms.
How many does a gallon weigh?
1 gallon = 4 quarts 1 quart = 0.25 gallon
Which one is heavier a gallon of fresh water or a gallon of sea water?
A gallon of fresh water is heavier than a gallon of sea water because fresh water is denser than sea water.
What is heavier heating oil or water?
Water is heavier.
What is heavier 1 gallon of water or 1 pound of sand?
1 gallon of water is heavier than 1 pound of sand. Water has a density of 8.34 pounds per gallon, so 1 gallon of water weighs more than 1 pound of sand.
Is water lighter than vegetable oil?
No water is heavier then oil.
Why does water go straight to bottom when mixed with oil?
Water is heavier than oil. Oil floats on water.
What weighs more a gallon of gas or water?
A gallon of water is heavier (about 7 1/2 lbs per gallon) than gasoline (about 5.8 lbs per gallon). This is also the reason that gas floats on top of water.
Is petrolium oil heavier than water?
Oil is less dense than water.
What is the difference in weight between a gallon of salt water and a gallon of fresh water?
salt water has more mass because of the added salt so salt is heavier :)
What weights more one gallon of water or one gallon of gasoline?
One gallon of water weighs more than one gallon of gasoline. Water has a higher density than gasoline, meaning it is heavier for the same volume.
What are some examples of a gallon?
Examples of a gallon include a gallon of milk, a gallon of gasoline, and a gallon of water.
Will water float on oil?
No, water will sink in oil because oil is less dense than water. This causes the water to be heavier and sink below the oil.
Other than density why can oil and water not mix?
oil and water never mix together. water is heavier than oil. so,oil float on the water.
