Effin Genious from Hahvahd 2009/09/23 17:48:41milk duh!!+2A gallon of milk weighs more than a gallon water, because milk has a higher specifc gravity (higher density) than water.

lol, you gave away the correct answer with this choice though!! lol
However, if we assume that the temperature and pressure are constant, though, and that we are dealing with whole milk, then indeed, a gallon of milk will weigh more than a gallon of water because whole milk is denser than water at a constant temperature and pressure.
The density of whole milk at 4.4 degrees Celsius is 1.035 kg/L, while the density of water at 4.4 degrees Celsius is 1.00 kg/L.
Since 1 Liter = 0.26417 gallons, we can calculate the actual weights (even though the densities are enough to provide your answer...).
For milk:
1.035kg/L * 1L/0.26417gal. * 1gal. = 3.958kg
For water:
1.00kg/L * 1L/0.26417gal. * 1gal. = 3.82kg
3.958kg > 3.82kg
Therefore, with the given assumptions, we can conclude a gallon of milk does indeed weigh more than a gallon of water.
Of course, one could argue that a gallon is a form of measurement and one can indeed be heavier than the other.
But I don't really care that much.
Edited: Here is what I found:
The density of milk (g/L) changes with temperature.
For example, the denisty of milk = 1.003073  0.000179t  0.000368F + 0.00374N,
where t = temperature in degrees C; F = percent fat; and N = percent nonfat solids
Question: If you collected milk from a Jersey cow (5.5% milk fat; 15% milk solids) and stored the sample at 4 C, how would the density of that milk compare with the density of milk from you collected from a Holstein cow (3.5% milk fat; 12.2% solids) and stored at 4 C? What if your milk samples were stored at room temperature (22 C)?
Which is heavier a ton of gold or a ton of feathers?
Both it's a ton duh!
Gallon = volume. Not at all alike.
If you have a ton of something and a ton of another they both weigh the same because it's a ton, the weight of a ton doesn't change no matter what objects you have to weigh
Take a bucket. Fill it up with air. Weigh it.
Volume is not weight.
it's all around us its got to be a substance which is not air
Weigh a bucket of feathers then. Is it heavier or lighter than a bucket of water?
do you get it?
A gallon is a measure of volume, just like a bucket is a measure of volume.
Kilograms, tons, pounds, etc... are measures of weight/mass.
Two things with the same weight weigh the same. Two things with the same volume do not ness. weigh the same.
crude oil=7lbs per gal
gallon n. ( Abbr. gal. ) A unit of volume in the US Customary System, used in liquid measure, equal to 4 quarts (3.785 liters)
Volume is the quantity of threedimensional space occupied by a liquid, solid, or gas.
Weight is the measure of the pull of gravity on an object
