how is the behavior of food coloring in the cool and heated water different? what caused the differences in…

Explanation:

Step1: Behavior in cool water

In cool water, food - coloring spreads slowly. This is because water molecules have lower kinetic energy at lower temperatures. The slower - moving water molecules impede the movement of food - coloring molecules, causing a slow diffusion process.

Step2: Behavior in heated water

In heated water, food - coloring spreads quickly. As the water is heated, water molecules gain kinetic energy and move faster. The faster - moving water molecules collide with food - coloring molecules more frequently and with greater force, facilitating a quicker diffusion.

Step3: Cause of difference

The main cause of the difference in behavior is the temperature - dependent kinetic energy of water molecules. Higher temperature means higher kinetic energy of water molecules, which enhances the rate of diffusion of food - coloring molecules.

Answer:

In cool water, food - coloring spreads slowly; in heated water, it spreads quickly. The difference is caused by the temperature - dependent kinetic energy of water molecules, with higher temperature leading to faster diffusion due to more energetic water - molecule motion.
