Two samples of water are prepared, one with red food coloring in one with blue when carefully combined the red colored water is able to float on top of the blue colored water which statement best explains this result the blue colored water is harder and more dense the blue colored water is cooler and less dense the red colored water is killer, more dense. The regular water is hotter and less dense.
The statement that best explains this result is: The blue colored water is cooler and less dense.
The statement that best explains this result is: "The red colored water is denser, and the regular water is less dense."
To determine the reason behind the red colored water floating on top of the blue colored water, we need to consider the properties of density and temperature.
Density is a measure of how much mass is packed into a given volume. A substance with higher density will sink below a substance with lower density. Temperature affects density as well - when a substance is heated, its particles move faster and spread out, decreasing its density, while cooling a substance causes its particles to slow down and come closer together, increasing its density.
Considering the given statement options:
1. "The blue colored water is harder and more dense" - Hardness is not directly related to the floating behavior of the colored water. Density, however, could contribute. If the blue colored water is more dense than the red colored water, it would sink instead of floating.
2. "The blue colored water is cooler and less dense" - This statement suggests that the blue colored water has a lower temperature, making it less dense. Since less dense substances tend to float on top of denser substances, this could explain why the red colored water is floating on top of the blue colored water.
3. "The red colored water is hotter, more dense. The regular water is hotter and less dense" - This statement does not provide a clear explanation since both waters are referred to as hotter and more dense. Also, we cannot assume the regular water is hotter.
Based on the given options, the statement that best explains the result is: "The blue colored water is cooler and less dense." This suggests that the blue colored water is colder and less dense than the red colored water, causing it to float on top.
