* Solubility: Solubility is the ability of a substance (like sugar) to dissolve in another substance (like water).

* Temperature: Temperature plays a key role in solubility. As the temperature of the water increases, the molecules move faster and have more energy. This increased energy allows the water molecules to break apart the sugar molecules more effectively, leading to a higher amount of dissolved sugar.

Think of it this way:

* Cold water: The water molecules are moving slowly, and it's harder for them to break apart the sugar molecules.

* Hot water: The water molecules are moving quickly, making it easier to break apart the sugar molecules and dissolve them.
