Answer:
Boiling waterBoiling water is an
example of a physical change and not
a chemical change because the water
vapor still has the same molecular
structure as liquid water (H20). If
the bubbles were caused by the
decomposition of a molecule into a gas
(such as H20-H2 and 02), then boiling
would be a chemical change.
