ex: does a gallon of milk weigh the same as a gallon of gasoline or motor oil? My thinking is no, b/c the gallon represents volume not weight, and Ive got someone telling me all liquids are equal in weight which Im not a scientist but that doesnt make any sense. help me solve the puzzle.

No.

Well I think they are saying a gallon= a gallon which is true. However, liquids have different densities therefore you wouldn't get the same amount due to the weight of the liquid.

No. You are correct, a gallon is only volume. Liquids, like other things, have different densities. 1 gallon of mercury, for example, weighs much less than a gallon of vegetable oil.

Nope. Some liquids are more dense than others; denser liquids weigh more. For example, mercury is a liquid at room temperature, and it is several times heavier than water. Most common (household) liquids weigh about the same as water though.

You are correct. For example a gallon of diesel weighs 7.6 pounds and a gallon of water weighs 8.34 pounds.
Maybe your friend is confused in thinking that a pound of water weighs the same as a pound of any other liquid. In that case your friend would be correct.

the density of liquid is variable affecting weight but not affecting volume. a gallon of 2 different liquids may not weight the same.

Well you are right and that person is an idiot. lol
They may be the same volume, but the weights or masses will be different if the chemical makeup of the solution is different. Different solutions have different densities and therefore different masses. It's a rather simple equation:
D=m/v
D = density
m= mass
v= volume

No. Different liquids have different masses depending on their densities. Parafin has a much lower density than mercury, so one gallon of parafin has a much lower mass than mercury. Weight and Mass are two different things...mass never changes, but things weight more on earth than they do on the moon due to the different gravitational pulls.

No, all liquids do not weigh the same. Just as all solid material does not weigh the same. some are more dense then others.
