Does  a gallon of milk weigh more than a gallon of water?

OH MY !!!\n\nPlease, don't believe the first answer.\n\nA gallon is a volume (physical size)...NOT a weight !\n\nSo, THE ANSWER IS YES, a gallon of milk DOES weigh more than a gallon of water...and this IS because it's density is higher.\n\n(Eg...a gallon of molten steel is heavier than a gallon of water...because it is more dense).\n\n(Eg...a bucket full of molten lead is heavier than a bucket full of pure oxygen...because it is more dense).\n\nCheck out the following link for a really good explanation !\n\nhttp://en.wikipedia.org/wiki/Density

Water at sea level weighs about 8.3 pounds per gallon.

technically mgs is a measure of weight while mls is a measure of volume.  So you would need to know the density of the liquid to properly calculate.  Different liquids have different densities.\n\nThat being said, 20 mls of water weighs 20 mgs.  I'm assuming that is a good enough approximation.

1 Gallon = 3.7854118 Litres.\n\n1 Litre of Water = 1 Kg (exactly)\n\nTherefore 1 Gallon = 3Kg, 785 grams \nor 8.346 Lb.

The density is 0.357 g/mL. This is because specific gravity is the ratio of the density of the unknown liquid to the density of water, 1.0 g/mL.\n\nIf, say, you wanted to know the density of the liquid in pounds per gallon, you would multiply 0.357 by the density of water, which is 8.320 lb/gal

The previous answer is not quite true. Indeed they are not the same. Weight is a measure of force, whereas mass is mass.\nHowever, you do not weigh the same everywhere on earth, although you would be hard pressed to tell the difference.\nYour weight at the top of everest, for example, is less than at sea level, because the force being exerted on you by gravity is less, allbeit only by a small amount.\nAlso, weight is a unit of force, whereas mass is not.\nMy weight may be 100kg, but my mass is (approx) 980N (at sea level), so weight and mass are actually never equal

Boats do NOT displace more water than they weigh - the amount of water displaced is EQUAL to the weight of the boat. Salt water is heavier per cubic meter than pure water or fresh water, so a smaller amount of salt water would be displaced for the same weight boat. If the density of the solution was extremely high, as in mercury, the boat would appear to sit on top of the liquid.

About 8 pounds.\n\nHere are more technical answers: \n\n\n8.34lbs \n\n1 gallon of fresh water is about 8.36 \n\nAccording to the 21st edition of The Machinery's Handbook, 1 galon of water weighs 8.337 pounds. \n\nTo answer this question more appropriately you would have to know the temperature of the water. As water cools it becomes more dense until it reaches 39.2 degrees fahrenheit. Below this temperature the density decreases and the water molecules spread apart. 1 liter of water/ice at will actually weigh less than 1 liter of water at say 80 degress fahrenheit. \n\nOne cubic foot of water contains 7.48 gallons of water, weighing in at 62.31 pounds. \n\nThe Handbook of Chemistry and Physics specifies the weight of 1 US gallon of water in air at 68 degrees F to be 8.32487 pounds or 3776.103 grams.

yes muscles weigh more than fat here is why....\n\n\nMuscle weighs more than fat because muscle cells that compose muscle are \ndenser than fat cells.  Why is this?  Because fat cell cytoplasm contains \nmostly oils (lipids), whereas muscle cell cytoplasm contains mostly \ncontractile proteins (myosin and actin) suspended in an aqueous (watery) \nenvironment.  Lipids in general are less dense than water.  You can prove \nthis by mixing salad oil with water in a bottle and shaking it.  \nEventually, the oil will separate from the water and float to the top to \nform a lighter layer floating on top of the water.  This lowered density of \nlipids make fatty tissue less heavy than muscle.

Since 1kg is equal to 1,000g, the 2kg watermelon weighs 2,000g.  The 2kg watermelon is twice as heavy as the 1,000g watermelon.

Well, a gallon of diesel is about 7 pounds at sea level.\nIf 1 gallon = 3.8 liters and a pound is 4.5 kilos, you can figure the rest, right?\n\nOoops, that was dumb. A pound is 2.2 kg. Duh. \n\nJust got to thinking about something else and had to revisit this question. Good thing others are on the ball tonight!

Lets use ice for example, if you put ice into a cup of water, rather that ice sinks, floats, or melts, you will still have a weight of the ice plus the water.\n\nSo the answer is 11 pounds. Even though the fish floats, it is still excerting a pound of pressure on the tank of water.

Milk is part water and part fat. The fat has a higher boiling point than the water, so the milk will not boil until it reaches a higher temperature.

What sort of gallon?\n\nYou can see from http://en.wikipedia.org/wiki/Gallon that there are several units that have that name

The primary reason it is not possible to drink a gallon of milk in an hour is related to stomach capacity. The capacity of the stomach is about 1 liter (Wardlaw and Insel. Pespectives in Nutrition, third edition, 1996). When stomach capacity is exceeded (whether by milk or any other food), the natural response will be vomiting. The stomach empties into the small intestine at a rate of about 1-3 milliliters per minute. When you figure how long it would take to clear a gallon of fluid from the stomach, it would take almost a day for it to enter the small intestine.
