The density changes due to differences in the density between cream and milk. Cream is lighter than water and milk is heavier than water. The average density of whole milk could be close to 1.024g per liter. When the cream is removed, the density of the milk goes up to about 1.036g per liter, while the density of the cream is about 0.968g per liter.
The density of milk increases.
how explain
the density of milk will increase
Cream, composed mainly from fats is separated from milk by centrifugation.
Preparation of cream from milk is a physical process.
The cream in full milk, is the richest part.
Gasoline
The fats (i.e. cream) from the milk will dissolve in the gasoline and the the resulting gasoline/cream solution will float on the water from the milk.
density of cream is lighter than milk
Cream, composed mainly from fats is separated from milk by centrifugation.
Fresh cream is separated from whole milk. Cream contains fat (saturated, polyunsaturated and monounsaturated fat), cholesterol, sodium, potassium, carbohydrate, vitamins A, B-12, B-5, D, C, and calcium, iron and magnesium

Cream can be separated from milk by either centrifuging or by allowing whole milk to stand. Both methods work on the principle that cream is lighter than milk.Because cream is lighter than milk, it rises to the top when the milk is allowed to stand. The cream can then be removed by skimming the top layer off.
Milk, the cream rises to the top therefore the cream is less dense
Cream is separated from whole milk. The main ingredient of interest in cream would be the butterfat. The amount of butterfat would depend upon the type of cream.
Fat free milk comes from a factory that has separated the fat out of the milk with a centrifuge. The fat is used to make cream.
A lactometer is an instrument used to measure the specific gravity milk; that is, the ratio of the density of the milk to the density of water. You can use a closed ended glass tube that is graduated. Milk is poured in and allowed to stand until the cream has formed, then the depth of the cream deposit in degrees determines the quality of the milk.
Cream is separated from whole milk by centrifuge or gravity. If you have unhomogenised milk, leave some to stand in the fridge and remove the cream from the top of the container the next day. Milk that has been homogenised will not give much cream in this way. Raw milk would work well.
It depends on the density of the milk which, in turn, will depend on the amount of cream that it contains. Or, if you get your milk from a dodgy supplier, the amount of water!
