The density of milk varies within the range of 1027 to 1033 kg m(-3) at 20° C.
PRODUCT ------------> Density (kg/L) at 20°C.
Heavy cream ------------> 0.994
Light cream ------------> 1.012
Half and half, fort ------------> 1.024
Half and half ------------> 1.020
Fortified skim ------------> 1.038
Skim milk, pkg ------------> 1.033
Homogenized milk ------------> 1.029
Producer milk ------------> 1.030

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.
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 cream floats above the surface of milk it means it is lighter or has less density just like ice floating on water.
Why this is confusing is cause cream kinda looks like solid more compact its confuses the brain but if you touch cream its like shaving foam so when less density is removed the density of remaining thing is sure is gonna increased.

The cream has lower density (or specific gravity) than milk and density of a mixture depends upon its constituents, depending upon their relative proportions. A decrease on the proportion of lighter constituent will result in the increase of the density of the mixture. So on the removal of cream, the density of milk will increase.

It will increase for sure. For all who thinks it will decrease.
Let d of milk = 2 g/l.
Let d of cream = 1 g/l.
So, d of whole =3 g/l or 1. 5 g/l.
Now, delete cream data, we have = 2 - 1= 2g/l.
So, d increases.
Let d of milk = 2 g/l.
Let d of cream = 1 g/l.
So, d of whole =3 g/l or 1. 5 g/l.
Now, delete cream data, we have = 2 - 1= 2g/l.
So, d increases.

Milk is a colloidal solution i.e. water (Cream) is dispersed in Fat (Milk). The cream is a dispersed phase and its density is less than water (water is a continuous phase).
So density increases.
So density increases.

Actually, milk has 3 component water, fat (cream) & solid (protein). When the cream has removed the weight of solid particle increases. That's why avg density of milk increases.

If the density of the creame is less then the milk then only it will increase. But I never thought or nor I am convinced about the density of milk being more then the creame.

The density of cream is more than the milk, so if it is separated from the milk, the density of the remaining milk will decrease.

The density of cream is more than the milk, so if it is seperated from the milk, the density of the remaining milk will decrease.
