A liquid that floats is lighter or less dense This happened because the molecules in the hot water are moving faster than the molecules in the cold water, therefore the diffusion in the hot water will occur sooner than the cold They may even realize that water is more dense and alcohol is less dense than the wax candle. They observe that the hot water floats on the room temperature water You can make colorful columns that demonstrate the concept of liquid density with just water, sugar and food coloring. So, water has more stuff, or molecules, stuffed into it than oil does, making it heavier than the oil. If we switch it up and The more solid that is added to water, the denser the solution is that is made, as more of the space between the water molecules is being filled. Density is mass (how many atoms are in an object) divided by volume (how much When the water-based food coloring is added, it is also more dense and can sink through the oil layer into the water beneath. If you have not already colored the rubbing alcohol, use a Key Concepts A liquid, just like a solid, has its own characteristic density. Add 1 drop of blue food coloring to the cold water Do oil and water mix? Oil and water have different densities. They observe that the hot water floats on the room temperature water and the cold water sinks. less dense (lighter) than water. This is because in hot water, the water molecules have more energy and are moving faster than the The food coloring, which is added to the water, is also denser than the oil, so it stays at the bottom of the glass or cup. Then mix the food coloring drops into the oil with a fork. A little food dye in one or both of the layers will show them mixing at the The layers from bottom to top: Honey (purple) - Most dense, sinks to bottom Dish detergent (blue) - Dense, but lighter than honey Water (green) - Medium density Vegetable oil (clear) - Less dense . Wash the food baster with some soap and water in the sink before moving on to the rubbing alcohol. The food coloring will not mix with the oil, but will mix when it enters the water The food coloring mixes through the hot water faster than it mixes with the cold water. The tiny water-based droplets of food coloring are denser than the oil, so th y begin to sink in the oil layer. If you weigh equal amounts or volumes of two different liqui ace of the water, it A more challenging density column includes liquids that will mix next to each other such as isopropyl and water. Procedure Demonstrate the density of two liquids by comparing the mass of equal volumes 1. The food coloring has a slightly higher specific gravity, or relative density, than water, so before it has time to diffuse, it tends to sink in the water. Materials Needed Two To create some more diverse color explosions, mix a range of food coloring colors with oil in a small bowl. However, due to diffusion and the hydrophilic nature of food coloring, it eventually begins to When a drop of food coloring is carefully introduced into still water, you often observe initial trails or “streamers” as the denser, more concentrated coloring begins to mix. Because the food coloring is made of The lower density of the ice makes it less dense than vegetable oil, so the ice sits in the middle of the container right on top of the vegetable oil. When the water is cold, and the diffusion rate is slower, more of the food coloring stays together in a plume falling to the bottom of the The food coloring has a slightly higher specific gravity, or relative The Food Coloring Test s in the oil, and spreads out on the surface of the corn syru . Students will combine the concepts of Here's what to do: Place a few ice cubes into a cup and add two tablespoons of water to make very cold water. The ood coloring is more dense than the oil so it sinks in Most food coloring substances are less dense than water, allowing them to initially float above the water surface. This experiment dissolves sugar in water to change the Students place hot and cold colored water into room temperature water. Food coloring is soluble in water, so once the droplets reach the Ever watched a single drop of vibrant food coloring hit a glass of water, transforming it into a mesmerizing, swirling masterpiece? It’s a common household phenomenon that instantly sparks When the water-based food coloring is added, it is also more dense and can sink through the oil layer into the water beneath. By observing how the different layers interact with each other, The density of the blue food coloring (or rather, the molecular weight, because when dissolved in water, the total density will be close to that of water) probably won’t stop the food coloring from being However, the food coloring that was added to the water turned out to be more dense than water and the dish soap and started mixing in with the milk Conclusion, salt water is much more dense than fresh water, in fact, the salt water never allowed the food coloring to reach below the ice cubes, and Since hot water is less dense than cold water, the hot water remains layered above the cold water and does not mix with it. Oil floats on water because it is less dense than water. e of how heavy it is for the amount measured. Food coloring is mostly water and mixes readily in the water. As the ice melts, the Students place hot and cold colored water into room temperature water. The food coloring will not mix with the oil, but will mix when it enters the water An experiment to teach kids about the difference in density between hot and cold water and the natural flow of warmer or cooler water.
