The table shows the density and volume of four liquid samples. The four liquids do not mix with each other. What is the order in which the layers will be formed, from top to bottom, if the four liquids are poured into a beaker and allowed to settle?

Sample A; Sample B; Sample C; Sample D

Sample D; Sample C; Sample B; Sample A

Sample C; Sample A; Sample D; Sample B

Sample B; Sample D; Sample A; Sample C

Answer:

The order of the liquids from top fo bottom will be B, D, A and C respectively.

Option D.

Explanation:

Liquid which are immiscible are arranged according to their density. The order of the liquid in the beaker won't depend on their volume. But this property of the liquid is solely dependent on their density. This is because of the pull of gravity. An equal amount of lighter liquid will have less mass than the same volume of denser liquid. So the heavier liquid will sink to the bottom.

Here in this question, the liquid B has density of 0.8g/ml, whereas the liquid D has the density of 0.9g/ml, the liquid A has density of 1g/ml and the density of liquid C is 1.08g/ml. So in the beaker, according to their density, the order will be B, D, A and C.
