What does it mean for a solution to be supersaturated? A. More solute has dissolved than should be possible.
B. More solute can still be dissolved in the solvent.
C. The dissolving speed was increased through heating.
D. The maximum amount of solute has been dissolved.

Explanation:

A supersaturated solution is a solution that contains more than the maximum amount of solute that is capable of being dissolved at a given temperature. The recrystallization of the excess dissolved solute in a supersaturated solution can be initiated by the addition of a tiny crystal of solute, called a seed crystal.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
