Is a gallon of milk heavier than a gallon of water or vice versu?

Answer 1

Milk weighs more because it is more dense.

Answer:

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.

Answer 2

yes, because they are both liquids and in the same size container. true. They are both liquids; at room temperature air is a gas. If you were to cool the room to the point where the air liquified, the water would have become solid long since. If you were to heat the room to something over 100C the water would vapourise. The density of water vapour is ~20% more than air at the same temperature and pressure, so the jug of water vapour would still be heavier than the jug full of air. Be that as it may, the question specifies water, not water vapour or ice.The straightforward answer to the question is yes. wow

Answer 3

A gallon of water is heavier than a gallon of milk. Water has a denser weight per volume compared to milk, so a gallon of water weighs more.

Answer 4

Yes, because Milk has protein and fat and water is just well... water.

Answer 5

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.

Answer 6

Because it's either denser or more dense. How do you pronounce it?

Answer 7

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

Answer 8

No, milk weight varies depending on the milk fat content.

Answer 9

The density of [cow's] milk varies, depending on the fat content,

but is always just slightly greater than the density of water.

Answer 10

Yes, because it has a higher density
