Water behaves differently in the range of 0°C to 4°C. As water is cooled from its liquid state, its density initially increases, following the general trend. This is because the molecules come closer together as their kinetic energy decreases. However, at around 4°C, something interesting happens. As water reaches this temperature, it starts to undergo a specific ordering of its molecules due to the arrangement of hydrogen bonds. These hydrogen bonds become more stable and cause the water molecules to form a lattice-like structure. This unique arrangement of water molecules at temperatures below 4°C increases the space between the molecules and results in a slight expansion of volume. Consequently, the density of water begins to decrease below 4°C, contrary to what is expected for most substances. At 4°C, water reaches its maximum density, where it is most compact and has the highest density.

This option is incorrect.
