Answer 1

The statement that best explains the result is:

The red water is warmer and is less dense.

When two liquids are mixed and one floats on top of the other, it is typically due to differences in density. Warmer liquids are generally less dense than colder liquids, which would explain why the red water (being warmer) floats on top of the blue water.
