This happens because the molecules are moving faster when they are heated up stirred.

Is adding food coloring to food a physical or chemical change?

Adding food coloring to a mixture would be considered a physical change. There are no new chemical bonds formed or broken. What you are creating is a new solution, just like adding salt to water and it dissolves. The salt stays salt, the water stays water. In this case what you are dissolving has a color to it so it changes the color of whatever you add it to but fundamentally the molecules that make up the food coloring stay the same.

How do you perform and observe brownian motion in the lab?

By combining any two visually distinct liquids, such as water and a drop of food coloring. Brownian motion is the constant motion of molecules, so if you fill a clear glass with water and then place one drop of food coloring into the water, you can watch as the food coloring diffuses throughout the water by Brownian motion.

Why is water clear and how does food coloring work?

Water is clear because protons can pass through the molecular structure of water uninterrupted. Food coloring on the other hand contains a molecular structure that can absorb protons. The molecular structure contains a high amount of conjugated electrons, which means that the electrons in the molecule can vibrate further than in a non-conjugated molecule. The ability to vibrate allows the molecules in food coloring to interact with protons.
