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 concentration depends on how much mass is dissolved in a given volume,as the volume increases,the concentration decreases.
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 it has a greater ability to dissolve more solute at a higher temperature,its concentration has increased.

As the volume of the solvent increases with temperature, the same amount of solute is now spread out in a larger volume, leading to a decrease in concentration.
