Two samples of pure water are mixed with food coloring. One sample is red, and the other is blue. When the two water samples are combined, the red water floats on top of the blue water. Which statement best explains this result? (1 point)
Responses
The blue water is warmer and is more dense.
The blue water is warmer and is more dense.
The red water is colder and is more dense.
The red water is colder and is more dense.
The blue water is colder and is less dense.
The blue water is colder and is less dense.
The red water is warmer and is less dense.
The red water is warmer and is less dense.
The correct statement would be:
The blue water is colder and is more dense.
To explain why the red water floats on top of the blue water, we need to consider the concept of density. Density is a measure of how tightly packed the particles in a substance are. In this case, we're comparing the densities of the red and blue water samples.
When two substances are mixed together, the one with higher density will tend to sink, while the one with lower density will float on top.
Given that the red water floats on top of the blue water, we can conclude that the red water is less dense than the blue water.
Now, let's analyze the given statements to determine which one best explains this result:
Option 1: "The blue water is warmer and is more dense."
Option 2: "The red water is colder and is more dense."
Option 3: "The blue water is colder and is less dense."
Option 4: "The red water is warmer and is less dense."
The first two options suggest that the warmer water is more dense. However, we know that warm water tends to be less dense than cold water. Therefore, options 1 and 2 can be eliminated.
Between options 3 and 4, the statement that best explains the result is:
Option 3: "The blue water is colder and is less dense."
According to this statement, the blue water being colder has a higher density. Since the red water is less dense, it floats on top of the blue water. Therefore, option 3 provides the most plausible explanation for the observed result.
