Which weighs more milk or water?
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.
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).
There are several ways you could determine the capacity of a milk jug: 1: Fill the milk jug with water and then transfer the water to a graduated measuring jug 2: take a bottle of known volume such as a soda bottle. Fill the soda bottle and transfer its contents to the milk jug to get its approximate capacity 3: weigh the empty milk jug and make a note of the weight. Then, fill the…
1 quart milk weigh 976 g, 1 ounce weigh 28g, 1 cup weigh 244g. As is typical these days, this questions was answered seemingly oblivious to the question asked. This person asked what a litre (maybe the British/French spelling confused answerer) of milk weighs. The beauty of the metric system is its relationship to water. A liter of water weighs 1 Kg (or 1000 g). Milk has a specific gravity of ~ 1.03 - ~1.05…
I'd say around eight pounds. Milk has a density between 1.02 and 1.05 grams/milliliter, so US gallon of milk would weigh between 8.5 to 8.8 pounds. In the imperial system of measure the weight of a Gallon of WATER is 10 Pound. MILK weighs very close to the same as water. In the Metric system, 1gallon equals 4.54 LITRE and weighs 4.54 Kliogram. The correct answer is therefore either 10 pound weight or 4.54 Kg…
