In STEM Integrated Science, what is the valid scientific law governing: Anomalous Expansion and Density of Water?
Water density increases linearly down to -20°C
Below 4°C, hydrogen bonds organize water molecules into an open hexagonal crystalline structure, decreasing density so ice floats and insulates aquatic life underneath
Hydrogen bonding is completely destroyed at 0°C
Water freezes from bottom to top in deep ocean basins
