Solubility and Temperature – Basic Principles
How it works
The solubility of a substance describes how much of it can dissolve in a certain amount of solvent (usually water). The solubility of many solid substances increases as the temperature rises, while the solubility of gases often decreases as the temperature rises. Solubility also depends on the substance itself and on the solvent. Saturated solutions contain the maximum amount of a dissolved substance at a given temperature.
Note
The solubility of a substance in a solvent depends on temperature: for solid substances, it usually increases with temperature; for gases, it often decreases.

An example
What usually happens to the solubility of sugar in water when the temperature is increased?
The solubility of sugar in water increases as the temperature rises, because more sugar can dissolve in warm water than in cold water.
