Final answer:
When water freezes, each molecule forms a stable hydrogen bond with its neighbors. Hydrogen bonding occurs between the positively charged hydrogen atom of one water molecule and the negatively charged oxygen atom of another water molecule. This creates a rigid and stable network in ice.
Step-by-step explanation:
When water freezes, each molecule forms a stable hydrogen bond with its neighbors. Hydrogen bonding occurs between the positively charged hydrogen atom of one water molecule and the negatively charged oxygen atom of another water molecule. This hydrogen bonding network becomes more rigid and stable when water freezes into ice.
