Here's why:
* Solubility: Solubility refers to the maximum amount of a substance (like salt) that can dissolve in a given amount of solvent (like water) at a specific temperature.
* Increased Temperature = Increased Solubility: As the temperature of water increases, the molecules move faster and have more energy. This increased movement allows them to break apart the ionic bonds holding the salt crystals together, enabling more salt to dissolve.
* Direct Relationship: The relationship between temperature and solubility for most solids, including salt, is a direct relationship. This means that as temperature goes up, solubility goes up.
Important Note: While warmer water dissolves more salt, there is a limit to how much salt can dissolve. Even at very high temperatures, there's a point where the water becomes saturated and can't dissolve any more salt.
