Answer
Yes, because changes in a solution's temperature cause changes in its volume.
Work Step by Step
When temperature of a solution increases, its volume increases because the added heat energy causes the molecules to be farther apart. Similarly, when temperature decreases, volume decreases as well because the molecules are closer together.
This causes molarity to change, since molarity is calculated as $\frac{m}{V}$, where $m$ is the moles of solute and $V$ is the volume of the solute, in liters.
