Three liquids of differing densities are studied. Samples of liquid 1 and liquid 2 are placed in a container together. Liquid 1 rises to the top. Another sample of liquid 1 is placed in a different container together with liquid 3. This time, liquid 3 rises to the top. If all three liquids are layered in one container, which of the following would be the correct order of the liquids from the bottom up to the top?
A. 2, 3, 1
B.3,2, 1
C. 1, 3, 2
D.2, 1,3

To determine the correct order of the liquids from the bottom up to the top, we need to examine the behavior of the liquids when they are mixed together.
From the given information, we know that liquid 1 rises to the top when mixed with liquid 2 and liquid 3 rises to the top when mixed with liquid 1. Based on this, we can infer that liquid 1 is the least dense, as it rises to the top when mixed with both liquids.
Now, let's consider the behavior of liquid 2 when mixed with liquid 1 and liquid 3. Since liquid 1 rises to the top when mixed with liquid 2, we can conclude that liquid 2 is denser than liquid 1. And when liquid 1 is mixed with liquid 3, liquid 3 rises to the top, which means liquid 3 is denser than liquid 1.
Putting these observations together, we can determine the order of the liquids from the bottom up to the top:
Liquid 2 (most dense) --> Liquid 3 --> Liquid 1 (least dense)
Therefore, the correct order of the liquids is:
D. 2, 1, 3
