chemical.....??

aaronq · Answer

i want you to think about it. lol

if you have liquid water and you freeze it (into ice), is it still water?

or if you have liquid water and you heat it and it evaporates (into steam) is it still water?

anonymous · Answer

yes......??

anonymous · Answer

no no no, nevermind, i think it is no......or, yeah maybe yes.... no, its no

aaronq · Answer

haha it's yes. The chemical composition doesn't change. $H_2O$ as liquid or vapour (gas) or ice (solid) is still water. So phase changes are physical, not chemical. And definitely not nuclear.
