Final answer:
Increasing temperature affects the rate of dissolution of a solute in a specific solvent. Solubility of solid substances generally increases with temperature, while the solubility of gases in liquids decreases with temperature.
Step-by-step explanation:
Increasing temperature affects the rate at which a solute dissolves in a specific solvent by increasing the kinetic energy of the solvent molecules. This leads to more frequent and forceful collisions between the solvent and solute, increasing the rate of dissolution. However, the effect of temperature on dissolution depends on the specific solute and solvent combination, as solubility can vary widely. In general, solubility of solid substances increases with increasing temperature, while the solubility of gases in liquids decreases with increasing temperature.
