Many solvents expand to occupy greater volumes with increasing temperature. What happens to the concentration of a solution made with such a solvent as its temperature is increased?
A. Since it has a greater ability to dissolve more solute at a higher temperature, its concentration has increased. B. The concentration of a solution increases as the solute fits into the new spaces between the molecules. C. Since it has a greater ability to dissolve more solute at a higher temperature, its concentration has decreased. D. Since concentration depends on how much mass is dissolved in a given volume, as the volume increases, the concentration decreases.
