* Physical Change: The sugar molecules are simply dispersing throughout the water molecules in the tea. The chemical composition of the sugar and the water molecules remain the same. No new substances are formed.

* Physical Property: A physical property describes a substance's appearance or behavior without changing its chemical makeup. Solubility (the ability of a substance to dissolve in another) is a physical property.

Here's a simple way to remember:

* Physical changes can be reversed (you can evaporate the water and recover the sugar).

* Chemical changes result in a new substance being formed (like burning wood, which creates ash and gases).
