What generally happens to the solubility of solids in liquids as temperature increases?

• A. It decreases
• B. It remains unchanged
• C. It increases
• D. It alternates

Answer: (C)

As temperature increases, the solubility of most solid substances in liquids generally increases. This phenomenon occurs because higher temperatures provide more energy to the molecules in the solid, causing them to move more vigorously. As a result, the increased kinetic energy facilitates the breaking of intermolecular forces within the solid, allowing the solid particles to interact more effectively with the solvent. When a solid dissolves in a liquid, the particles of the solid must overcome the attractive forces holding them together. Higher temperatures help overcome these forces, thereby allowing more of the solid to dissolve in the solvent. There are exceptions where the solubility behavior can vary, particularly for certain salts or compounds under specific conditions, but the overall trend observed in most cases is that solid solubility in liquids increases with temperature.
