Answer:
Water is a great solvent, able to dissolve many substances.
For all three states, water's boiling and freezing points make it easy to find (solid, liquid, and gaseous).
Water has a high specific heat. This allows water to absorb and release heat slowly, regulating its environment's temperature.
Water's transparency allows light to reach the life forms submerged in it. This is vital for ocean, lake, and river plant life.
Water is neutral in nature. With a pH of 7, it is neutral.
Water is a vital resource for plants, animals, and humans because of its unique properties and abundance on the planet.
