(A) Increases
(B) Decreases
(C) Remains the same
(D) May increase or decrease
Ans. (A) Increases
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.
In the same volume more cream can be fixed than milk because its constituents are closer to each other than milk. Then, how the density of milk can be greater?
ReplyDeleteFor instance, just drop some cream in to milk. It will settled down after some times. Why? Because it has higher density.
