Milk weighs more because it is more dense.


Milk is a complex mixture containing sugars, salts, lipids and proteins. As a consequence its mass/volume or density and its specific gravity vary with the type of cow and the specific cow.

To minimize variables the milk or water must be at the same temperature as the density of water increases as the temperature lowers (until 4oC). The density of milk = 1.003073 - 0.000179t - 0.000368F + 0.00374N, where t = temperature in degrees C; F = percent fat; and N = percent nonfat solid. Comparing the resulting data for several types of cattle, the mean specific gravity of Holstein milk at 20 C/20 C is 1.0330 (range 1.0268 to 1.0385) and for Ayrshire milk is 1.0317 (range 1.0231 to 1.0357), while Jersey milk also has a mean of 1.0330 (range 1.0240 to 1.0369). [see Sherbon JW, Physical Properties of Milk, Chapter 8 in Wong et al, 1988]

Milk is more dense than water by 2% to 4%. This is about the weight of penny per litre.

A gallon of whole milk weighs 8.63lb per gallon. Water weighs about 8.33 lbs per gallon so milk weighs about 5 ounces more per gallon than water.

Type your answer here... they both weigh the same because if you pour the same amount of milk as water they would both weigh

A gallon of milk. Milk is denser than water, and water is 1kg per litre. Since 1 pound is equal to 0.45359237 kg, and a gallon is much more than a litre, a gallon of milk must weigh more than a pound. A gallon of milk weighs 8.6 pounds, 860% the weight of a pound of flour.

Sand weighs more then water

the thing that weighs a gallon is a gallon of WATER or a gallon of milk.

alcohol weighs more than water!

Cream weighs SLIGHTLY more than milk does because of the milk solids and fats. But you'd need a VERY precise scale to demonstrate that.

Milk. In fresh milk cream floats on top of the milk. The cream doesn't rise as stated, the milk sinks. If water is added to gasoline or diesel the water sinks to the bottom, the fuels do not rise. Same with milk and cream, the lighter fluid will sink leaving the heavier fluid on top.

At 20 oC or 293 K or 68 oF, the densities of water and raw milk are 0.998 and 1.03 g/cm3 respectively. As the density of raw milk is slightly more than that of water, 1 gallon of milk will weigh slightly more than 1 gallon of water. However, for practical purposes, it can be considered that, both will weigh the same (as the densities are almost the same).

Cream weighs less than the same volume of milk. If it is separated from the milk, cream floats on top because its specific gravity is less than that of milk.

well water weighs more becuz the oil happens to be light

Water, milk, more water, more milk, koolaid, tea and finally more water!!!!!

well 1kg of water= 1 litre, though milk weighs about 30 grams more so so 1,3 litres

1 liter of water weighs 1 kilogram or 35.27396 ounces. Milk is not water, but very similar.

Milk contains more buffers than water

Water 1 gallon of fresh water weighs 8.34 pounds

If you sink, then you weigh more than your volume of water.If you float, then the volume of water you displaced weighs the same as you weigh.

A gallon of water weighs 8 pounds.

the water weighs more, ice is an 'expanded form of water- because it is less dense there is more space between the molecules and therefore lighter

1 liter of retail milk (2% or 3% milkfat) weighs about 1.035 kilograms. (just slightly heavier than water, as milk is mostly water)

it basicly depends on the quantity: if there is more water and less bricks then the water weighs more if there are more bricks than water then the bricks weigh more if the bricks and water are in equal amount, then if the water is really dense it may weigh more... it varies

water diolutes the milk and makes it more water-ey... Water does this to every liquid

A cup of water weighs 8.3 ounces.A cup of ice weighs 7.7 ounces.
