To the underlying reasons that, because of their bonding energy of different molecular bonds between water molecules need energy weak damage, and iron atoms bond formed between the destruction of atomic energy for strong, so the bond energy of molecular water at room temperature has been reached, it

It would be a simple melting point of view that is different.

Said toward the intrinsic reason that, is because respective Cheng Jian energy is different, between the hydrone the molecular linkage destruction needs the energy to be weak, but between the hard atom forms the atomic binding destruction needs energy, therefore under the normal temperature the hydr

To the underlying causes of said, because their different bonding energy, molecular link between damage of water molecules requires energy, and formed between iron atoms and atoms key destruction requires energy, so the bond energy of water molecules at room temperature has been reached, so the liqu
