hey mate here is your ans:-
1. burning candle: the wax is melting, which is a physical change, and it's combusting, which is a chemical change.
2.Digestion is another example of both. Food is physically broken down by chewing and chemically broken down by digestive enzymes in the saliva and acid in the stomach.
3. A third example is weathering in nature. Rocks are physically changed by wind, running water, expansion of ice as it freezes, abrasive wind and water-borne sediments. They are chemically changed by oxygen, acid rain and acidic compounds produced by decomposers
hope this helps you.
plz mark this as brainliest.
