the chemical composition does not change.
Melting is a physical change.
Melting is not a chemical change because the chemical formula of water remain unchanged.
Physical because none of its chemical property's are not changed. Its still ice, just melted
no unless there is a chemical change but there isn't. only a physical change has occurred

They're both physical changes. Phase changes are always physical changes. Chemical changes only involve chemical reactions - a change in the identity of the substance. That's why phase changes are physical changes. Ice cream remains ice cream when it melts.
Physical change
it is a chemical change
chemical change
The chemical structure is unchanged.
the chemical composition does not change.
Partly physical, partly chemical. Melted butter has different chemical properties than solid butter. The melting process, as with chocolate, is not reversible. Proteins in the butter can become denatured, and isomerization of lipids to trans fats occurs. Phase change is a common example of physical change, but chemical change also occurs in this case.
