Answer 4

Sugar and water is a physical change because there is "no change" in its identity.
When water evaporates, the sugar crystals will still remain the same as sugar.

Physical Change = No Change (in chemical components) & it can be turned back to its original substance.

Chemical Change = Forms a new substance

All answers are correct.
I would like to add that chemical change can also have a color change.
In this case, there is no color change. We know for sure that it is a physical property.
