What is heavier gallon of water or gallon of oil?

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.

What weighs more one gallon of concrete or one gallon of water?

Steel is heavier than concrete for the same volume, however steel buildings are generally lighter. This is because steel buildings utilize high strength of steel, so volume of steel in steel buildings is much smaller than volume of concrete in concrete buildings. In another words in steel buildings much less volume of material is needed for the same strength compared to concrete buildings.
