Liquids are poured into a container and separate. They form a green layer on the bottom, a blue layer in the middle, and a red layer on the top. What's true about the density of the liquids?

Question

Question 18 options:

A)

The blue liquid is the least dense.

B)

They all have the same density.

C)

The red liquid is the least dense.

D)

The green liquid is the least dense.

Answer 1

In a setup where liquids are poured into a container and separate into distinct layers, the order of the colors indicates their relative densities. Generally, the liquid with the highest density goes at the bottom, while the least dense liquid floats on top.

In this case:

• The green layer is at the bottom.
• The blue layer is in the middle.
• The red layer is on the top.

This means that the green liquid is the densest, the blue liquid is less dense than green but denser than red, and the red liquid is the least dense.

Based on this reasoning, the correct answer is:

C) The red liquid is the least dense.
