Hey Mate..!!!!
____________
Here is ur answer:
__________________
A change cannot be both physical and chemical but it can occur simultaneously in nature.
For example: Burning of a candle it will burn down the wax changing the physical state of the candle and the combustion process will fall into the category of chemical change.
Another example is digestion as physical food is chewed which change the shape of it and the whole process is a chemical cycle.
