Final answer:
Solid water, or ice, has the most number of hydrogen bonds between the hydrogen atoms of water molecules. When water freezes, the hydrogen bonds become more rigid and form a well-defined network, creating empty spaces between the molecules and increasing the overall volume of the solid.
Step-by-step explanation:
True. Solid water, or ice, has the most number of hydrogen bonds compared to liquid or gaseous water. Hydrogen bonds occur between the hydrogen atoms of water molecules. When water freezes, the hydrogen bonds become more rigid and form a well-defined network, creating empty spaces between the molecules and increasing the overall volume of the solid.
