The decay of organic matter such as leaves is a chemical change.
it depends its physical if you cut it and its chemical when you burn it
Leaves change colour because the green pigment (chlorophyll) is degraded, then other pigments like anthocyanins (red or purple) and carotenoids (yellow) are exposed. So the change is more chemical than physical. Leaves going brown are also caused by chemical changes, but it also means the leaf cells are dead or dying.
Yes, it is a chemical change; a chemical reaction occur.
Depends whether you have any liquid or change on your hands i.e. soap. If not and her hands have absolutely nothing on them, then probably not.
It is a chemical change, a degradation of the compounds from the leaf.
Chemical
The change is leaf color is a chemical change.
Because the leaf is not burning.

Chemical. It has to do with the closing of the part that connects the leaf to the tree and the lack of nutrients causes the leaf to turn colours.

Physical Property
Photosynthesis makes a leaf green so when it turns brown it has stopped doing photosynthesis so most likely it is chemical change. Helpful enough? :|
