Hello friends Good Morning
Dissolving sugar in water is an example of a physical change. Here's why: A chemical change produces new chemical products. In order for sugar in water to be a chemical change, something new would need to result. A chemical reactionwould have to occur. However, mixing sugar and water simply produces... sugar in water! The substances may change form, but not identity. That's a physical change.
One way to identify some physical changes (not all) is to ask whether the starting materials or reactants have the same chemical identity as the ending materials or products. If you evaporate the water from a sugar-water solution, you're left with sugar.
I hope my answer help to u and right
