Explain why changes of state are considered physical transitions and not chemical processes?

This is because when a substance, such as water, is changed to a solid (ice) it keeps its same, original properties! A chemical change involves changing the substance into a completely new substance. Water, on the other hand, can go from a solid, to a liquid, to a gas without changing its properties, only its state!

∙ 12y agoThey do not change into any other element/molecule, they just change form. Ice is still water, just in a solid state. Chemical changes change the identity of the substance.
Wiki User
∙ 13y agoBecause a change of state is
A) Easily reversible
B) simply a restructure of the same compound.
Wiki User
∙ 12y agoBecause it can change from one state to another.
Wiki User
∙ 12y agoThe relative abundance and structure of molecules stays the same, only the molecules' attachment to each other change, thus it is physical and not chemical

∙ 11y agoA change in state does not produce a new substance.
