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

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

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

Option D.

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.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
