The statement that solubility generally increases with increasing temperature is indeed true for most solids dissolved in liquids. This phenomenon occurs because higher temperatures typically provide molecules with greater kinetic energy, facilitating the breaking of intermolecular forces and allowing solute particles to disperse more easily throughout the solvent. As the temperature rises, the solvent molecules move faster, increasing interactions with solute molecules and thereby enhancing solubility.

However, it's important to note that this trend can vary with different substances. For some gases, solubility actually decreases with rising temperature due to increased kinetic energy allowing gas molecules to escape from the solution more easily. Thus, while the statement holds largely true for solids and liquids, it's conditional for gases, which is why a nuanced perspective is essential. In the context of this question, the broad statement that solubility generally increases with increasing temperature effectively captures the behavior of many common solutes.
