Question

base your answers to the questions on the information and diagram below. a student was given samples of four different liquids, a, b, c, and d. the student poured equal amounts of two different liquid samples into several test tubes. the results are shown in test tubes 1, 2, 3, and 4. when equal amounts of liquids a, b, c, and d were placed into test tube 5, the liquids separated into four layers. a diagram of test tube 5 appears below. on the blank lines next to each layer, list the final order of the liquids as they would appear in test tube 5.

Explanation:

Step1: Analyze test - tube 1

In test - tube 1, B is on top of A, so density of B < density of A.

Step2: Analyze test - tube 2

In test - tube 2, C is on top of B, so density of C < density of B.

Step3: Analyze test - tube 3

In test - tube 3, D is on top of B, so density of D < density of B.

Step4: Analyze test - tube 4

In test - tube 4, D is on top of C, so density of D < density of C.

Step5: Determine the order

Combining the above, the order from least dense to most dense is D, C, B, A.

Answer:

Top - layer: D
Second - layer: C
Third - layer: B
Bottom - layer: A
