What happens to the chemical structure of water when it changes states

When water changes to a solid or gas, it's said that water changes to a different state of matter

Explanation:

Even when water physical form changes, the molecules stay the same. Water's molecules contains two hydrogen atoms that is bonded with one oxygen atom.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
