∙ 7y agoI think it is a physical change because if it's a chemical change it would be a whole new substance but it's only a change of color.
Re: No it can't be a physical change because it's irreversible. There is a chemical reaction occurring in the leaves, so it should be a chemical change.

∙ 13y agoThis could be considered a trick question! A leaf turns brown because the chlorophyll content of the summer leaf is chemically degraded and therefore no longer has a green color. This allows one to see the brown pigment that was in the leaf during the summer but was invisible to normal inspection because of the overwhelming amount of green from chlorophyll.

∙ 11y agoNo, its not a chemical change it is a physical change, it is still a leaf.
