Properties Of Water: Characteristics and behavior of water

Water is a transparent, odorless, and tasteless compound made of hydrogen and oxygen. It is vital for life and covers over 70% of Earth's surface, with only 3% being freshwater. The water cycle, driven by solar energy, involves processes like evaporation, condensation, and precipitation, facilitating the continuous movement and state changes of water on Earth.
