Which property of water causes it to expand when it freezes making ice less dense than liquid water?
A
Hydrogen bonding creating a crystalline structure
B
High specific heat capacity
C
High surface tension
D
High viscosity
Correct Answer: Option A — Hydrogen bonding creating a crystalline structure
Explanation:
Water expands when it freezes because hydrogen bonds arrange water molecules into a hexagonal crystalline lattice that takes up more space t...
Water expands when it freezes because hydrogen bonds arrange water molecules into a hexagonal crystalline lattice that takes up more space than the same number of liquid water molecules.
