A physical change.
A physical change is when the compound stays the same, but the state of the compound changes. For example, when ice melts, it turns to water. Ice and liquid water are the same thing.
A chemical change is when two or more elements or compounds combine to form a new compound. If you take two H2 (diatomic Hydrogen) particles and one O2 (diatomic oxygen) particle, you will get two particles of H2O or water. The hydrogen and oxygen is no longer present, they combined to form a new compound. This is a chemical change.

it's a purely physical change. the water is still water, if it's solid or liquid. the only difference is that by melting the ice you make the water molecules move faster and thus create a liquid.

It is a physical change only; the ice, which is a form of water, becomes liquid water - it has not changed to another substance.

I believe that the change is purely physical; nothing is happening to the water molecules themselves.

It's a physical change. It's still H2O, whatever its form.
