Question

How is the behavior of food coloring in the cool and heated water different? What caused the differences in their behavior?

Answer 1

Answer:

In hot water, the food coloring diffuses (spreads out) through the water quickly. In cold water, the food coloring diffuses (spreads out) through the water slowly. The hot water causes the food coloring to diffuse faster. At higher temperatures, particles move faster.

Answer 2

The behavior of food coloring in cool and heated water is different as it spreads faster in heated water. This is because of the difference in the rate of diffusion.

What is diffusion?

• The movement of particles along a concentration gradient, i.e, from a higher concentration to a lower concentration, is called diffusion.
• Diffusion is an important process in many living beings. It is how the gases diffuse in and out of cells in plants and animals.

Factors Affecting the Rate of Diffusion

• The rate of diffusion depends on the following factors:

1. The gradient of concentration between the media.
2. The permeability of the membrane between the media.
3. Temperature
4. Pressure

Temperature Dependence of Diffusion

• The rate of diffusion is directly proportional to temperature because the rate of diffusion increases with an increase in temperature.
• At higher temperatures, the particles have more kinetic energy and thus their movement is more rapid.
• This leads to faster diffusion of the particles.
• So, when food coloring is added to heated water, it will diffuse faster than in cool water due to the higher energy of the particles.

Therefore, the food coloring spreads faster in heated water as compared to cool water.
