Physical, because the chemical composition of the tree did not change.
So, ripping a piece of paper into pieces is physical. You still have paper, its just smaller. Lighting the pieces on fire is chemical. Now you have some carbon and who know's what else, plu the carbon you lost in the fire.
On a test though, don't be fooled by the trick questions about water. Boiling water into steam is still a physical change. The molecules are still two hydrogen and one oxygen, they are just moving faster and are farther apart.

is the tree branch still a tree branch, made of wood? Yes. It still is. It is just in a different physical place. Therefore it is a physical change!
Now if that branch caught on fire... it wouldn't be a branch anymore, it would be ashes and heat. THAT would be a chemical change.

Physical because only the appearance of the tree changed, Not the Chemical or genetic make-up...Oh wow... I did learn something in school.

Physical change. The wood is still wood. If the tree burned down, that would be chemical change.

It is a physical change, but chemical changes are soon to follow. Fluids are no longer flowing through the branch, so it will die and begin to decay soon.

physical- the tree isnt chemically changing into something.

Evolution, by technique of itself, does no longer disprove the life of god or gods. If some thing can't come from no longer some thing, then the position did god come from? Oh? He continuously existed? So he got here from no longer some thing? So if god would not want a reason, then why does the universe? i might want to easily as easily argue that the universe is eternal. lol why might want to there be no effects? What reasoning are you utilizing to make this decision? Your god would not want a reason, correct? So why does the universe? by technique of ways, you in user-friendly words requested a question. You did not clarify your reasoning. How did you recognize that this hypothetical god is unaffected? by technique of ways, you're being quite obscure. Please outline "result." you've really round reasoning. lol. God is eternal via the undeniable fact that is uneffected. To have an a universe with result, you want an uneffected god. lol. You, your self, attempt to outline the criteria by technique of which a god ought to exist. regrettably you aren't any further infallible (as a trifling man or woman). for this reason, we require evidence of this declare - no longer some round reasoning. Haha advert hominem attacks? you would as well say "Ughh... you're correct, i do not have evidence to diminish back up my claims." yet that is okay. i am going to verify between the lines for you. Have a strong one!

It is initially a physical change - then as the brnach dies - it is a chemical change!!

that is a phsyical change, because the tree's identity isn't changing, just it's appearence. it can always grow another branch.

its a physical because you could glue it back on the tree whereas if it was burned you could never bring it backm to its former state
