When water (H2O) freezes into ice, the following stays the same:
- **Identity of the H2O**: The chemical composition of water remains the same; it is still H2O, regardless of whether it is in liquid or solid form.
The other options change during the transition from liquid water to ice:
- **Energy of the H2O**: The energy decreases as water freezes, as it releases heat (latent heat of fusion).
- **Arrangement of the H2O**: The arrangement of water molecules changes significantly; in liquid water, the molecules are more loosely arranged and move freely, while in ice, they are arranged in a more structured, lattice formation.
- **Property of the H2O**: Various properties such as density, shape, and thermal conductivity change when water freezes.
So, the correct answer is that the **identity of the H2O** stays the same.
