Answer:
observed?Brownian motion is the random movement of particles suspended in a fluid due to collisions with other molecules in the fluid. In this case, the food coloring molecules are suspended in the water, which is a fluid, and the random movement of the water molecules causes the food coloring molecules to move around in a random pattern. This movement is similar to the movement of atoms in a gas or liquid, which is also driven by Brownian motion. So, the concept of Brownian motion helps to explain the random movement of the food coloring molecules in the water, as observed in the experiment.
