Question

Why would you expect the rate of diffusion to increase with temperature? Can you give an example, such as the fact that you can dissolve sugar more rapidly in hot water?

Step-by-Step Solution

Answer

The rate of diffusion increases with temperature due to an increase in kinetic energy.

Step 1: Diffusion

Diffusion is when the particles move from higher concentration to lower concentration. The rate of diffusion depends on the temperature.

Step 2: Explanation

The increase in temperature increases the kinetic energy of the molecules of fluids. As the kinetic energy increases, the particles move faster, and the rate of diffusion increases.

Teabag is diffused more quickly in hot water. The high temperature increases the kinetic energy of the teabag and the water molecules.

Thus, the diffusion rate increases and the teabag is diffused more quickly in hot water.
