Water has unusual properties that make it essential for life. It has a high heat capacity allowing it to absorb large amounts of heat with only small changes in temperature, helping regulate temperatures for living things. Water also has an unusually high boiling point and freezing point compared to similar molecules its size, existing as a liquid over a wide range of temperatures that are livable. These unique properties are crucial for biological and chemical processes on Earth.
