This frosty enigma refers to a common substance found in nature, one that plays a vital role in our world. When exposed to flames, this solid form of water doesn't burn because it is fundamentally incapable of combustion. Fire requires fuel to react with oxygen, and water, being the product of hydrogen and oxygen's complete reaction, has no further chemical energy to release. Instead, the heat from a fire causes it to undergo a phase change, transforming from a solid into a liquid at its melting point of 0°C (32°F), and then into a gas (steam) if heating continues.
The second part of the riddle highlights another fascinating property. Unlike most substances, which become denser when they freeze, water expands as it turns into its solid state. This is due to the unique way water molecules arrange themselves into an open, hexagonal crystal lattice when frozen (Review). This structure means that ice is less dense than liquid water, allowing it to float rather than sink.
This unusual characteristic is incredibly important for life on Earth. Imagine if ice sank; lakes and oceans would freeze from the bottom up, potentially eradicating aquatic ecosystems. Instead, floating ice forms an insulating layer on the surface, protecting the water below and allowing marine life to survive through cold periods. So, whether faced with heat or surrounded by its liquid counterpart, this substance simply changes form or remains afloat, never truly succumbing.
