Final answer:
The statement is false; increasing temperature does not necessarily increase molarity. Molarity is defined by the concentration of solute in a solution, not by the kinetic energy or entropy which are the properties that increase with temperature.
Step-by-step explanation:
The statement that when the temperature of a substance is increased, the molarity will also increase is false. Molarity is defined as the number of moles of solute per liter of solution, and it is not directly affected by temperature. Instead, as the kinetic-molecular theory suggests, increasing temperature results in more extensive vibrations of particles in solids, and more rapid translations in liquids and gases, meaning the average kinetic energy and the entropy increase, not the molarity. Solubility, however, which is the amount of a substance that can be dissolved in a liquid, often increases with temperature for many solids, but this does not mean the molarity of the dissolved substance automatically increases.
Therefore, the correct answer to the question is:
