Question
ice floats in or on liquid water because:
magic is real
ice has more hydrogen bonds to space out the molecules than liquid water
ice has fewer hydrogen bonds keeping the molecules closer together than liquid water
When water freezes to form ice, each water molecule forms more hydrogen bonds (four) compared to liquid water (about 2.3). These hydrogen bonds in ice hold the water molecules in a more open, hexagonal lattice structure. As a result, ice has a lower density than liquid water. Objects with lower density float on substances with higher density. So, ice floats on liquid water because ice has more hydrogen bonds that space out the molecules (lowering its density) compared to liquid water.
