Answer:
Burning sugar results in a chemical reaction
Explanation:
Flammability, odor, and density are just a few examples of characteristic properties of a substance. A chemical reaction occurs when molecules interact with one another and the molecules change. For example burning sugar results in a chemical reaction because the properties of cube B changed when it was burned. This change in solubility shows that cube B must be a different substance than cube A because of the chemical reaction that occurred when cube B was burned.

The water molecules move from areas of high concentration to areas of low concentration to make an equivalent between the two.
I hope this helps at least a little :D
Answer:
it's related to the factors of diffusion, in this case...
the molecule is small, the mass of it is a factor of diffusion, since it's smaller, it can diffuse quickly, since it has less weight, so it moves faster.
When the cell increases in size, the volume increases faster than the surface area, when there is more volume and less surface area, diffusion takes longer and is less effective.
