Answer:

When liquid water (H2O) freezes into a solid state (ice), it appears changed; However, this change is only physical as the the composition of the constituent molecules is the same: 11.19% hydrogen and 88.81% oxygen by mass. ... The melted ice cube may be refrozen, so melting is a reversible physical change.
