1. Arrange the following unknown fluids in the correct order of how they would separate in a beaker, listed from bottom to top, based on the given measurements.
Answer: B
A, C, B
The correct order of the unknown fluids in a beaker, from bottom to top, is A, C, B. This arrangement is determined by the densities of the fluids, where fluid A is the densest and fluid B is the least dense.
A) A, B, C
This option incorrectly places fluid B above fluid A, which contradicts the principle that denser fluids sink below less dense fluids. Given that A is denser than both B and C, this arrangement cannot be correct.
B) A, C, B
This is the correct arrangement, as fluid A is the densest and therefore sits at the bottom. Fluid C, being less dense than A but denser than B, occupies the middle position, while fluid B, the least dense, floats at the top of the beaker.
C) C, A, B
This option places fluid C at the bottom, which is incorrect since fluid A is denser than C. Thus, this arrangement fails to adhere to the correct ordering based on density.
D) B, A, C
This arrangement incorrectly positions fluid B at the bottom, which is not possible given that A is denser and should be placed below both B and C. Therefore, this option does not reflect the correct separation order.
Conclusion
The correct order of fluids from bottom to top is A, C, B due to their respective densities. All other options fail to correctly represent the principle of density separation, placing denser fluids incorrectly above less dense ones. Therefore, option B is the only valid choice based on the provided measurements.
