Question

Use the particle model to explain diffusion of sugar in water.?

Answer 1

Through random motion of particles...

Explanation:

When we put sugar in water and stir it, the sugar will dissolve in the water. This is because of diffusion, as the sugar will move down a concentration gradient. This means that it will move from a high concentrated area to a region of lower concentration.

Also we have to take in account of Brownian motion. The random movement of water molecules collide with the table sugar or fructose molecules, therefore also distributing them randomly everywhere, and dissolving the molecule in the process.
