Fresh milk has several parts that a farmer can separate and sell. A farmer removed the top layer of fat from fresh milk. What property does the farmer use to separate the fat from the rest of the milk?

The fat has a lower density than the other parts of the milk.

Explanation:

Milk is a dairy product which is produced by the mammary gland of mammals such as cow, goat, pigs and even human beings used for the nourishment of their younger ones. Milk gotten for cow is usually processed and consumed by man. It's constituents includes the following:

-> water,

-> lactose

-> fat

-> protein and

-> minerals.

The fat component of milk can be separated by simply allowing the fresh milk to stand for a period of time and the top layer of fat removed. This is possible because fat has a lower density than the other parts of the milk. In the dairy processing, when fresh milk is allowed to stand for a period of time, the fat globules would begin to rise to the surface in a phenomena called creaming.
