Hot vs Cold Water Experiment (Chemistry)

In this experiment, you can visualize the difference in density between hot and cold water. Using the food coloring and a thermal infrared camera you can really see what is happening at the particulate level. ▶️ Get the materials to perform your own Hot vs. Cold Water experiment: https://www.beardedscienceguy.com//ho... ▶️ See Hot vs. Cold Experiment - Part 2 with oil and water here:    • Hot vs Cold Experiment with a Twist (Chemi...   ▶️ Hot vs. Cold Water Density Experiment Procedures: Step 1: Gather supplies--two glasses of the same size, a hard piece of plastic, and two different colors of food coloring. Step 2: Fill one glass with cold water to the brim, so the water is bubbling over the top of the glass. Step 3: Fill the second glass with hot water to the brim as well. Step 4: Stir in food coloring to the cold water. Mix well. I used blue for the cold water. Step 5: Stir in a different food coloring to the hot water. Mix well. I used red for the hot water. Step 6: Place the thin, flat plastic on top of the hot water glass so you can flip it upside down without spilling the water. Step 7: Carefully turn the hot water glass upside down, holding the plastic in place, and set it directly on top of the cold water glass. Make sure the rims line up all the way around. Step 8: Carefully remove the plastic from between the two glasses to allow the water to mix, and observe. ▶️ How the hot vs. cold water density experiment works: You'll notice that the hot and cold water don't mix after the plastic piece is removed, with hot water staying on top and cold water staying on the bottom. That's because the density of the cold water has particles packed a little closer together than the hot water, and gravity is pulling them down now. it's time to repeat the experiment only this time we're going to reverse it so go ahead and fill up your cups with hot water and cold water again and then use the food coloring to make the hot water red and the cold water blue Try reversing the experiment with the cold water on top instead, and you'll see the cold water and hot water start mixing quickly. This is because the higher density cold water starts falling down through the lower density hot water. The temperature of the hot water stays hot and the temperature of the cold water stays cold. ------------------------------------- SUBSCRIBE for more cool science experiments! https://www.youtube.com/c/BeardedScie...
