Here's why:
* Solubility: The solubility of sugar (and most solids) increases with temperature. Hot water molecules have more energy, allowing them to break apart the sugar molecules more easily and dissolve them.
* Rate of Dissolution: Higher temperatures also increase the rate of dissolution, meaning the sugar will dissolve faster in hot water.
Practical Tip: If you want to dissolve mints quickly, use hot water. However, be careful not to use water that is too hot, as it could damage the mints.
