Formula: Water's chemical formula is H₂O. This means each water molecule is made of two hydrogen atoms and one oxygen atom.

States of Matter: Water can exist in three states: solid (ice), liquid (water), and gas (steam or water vapor).

Boiling and Freezing Points: Water boils at 100°C (212°F) and freezes at 0°C (32°F) under normal atmospheric pressure.

Density: Water has a density of about 1 gram per cubic centimeter (g/cm³) at 4°C. This is why ice floats on water; ice is less dense than liquid water.

Solvent: Water is known as the "universal solvent" because it can dissolve many substances, which is crucial for life processes and various chemical reactions.

pH Level: Pure water has a neutral pH of 7, meaning it is neither acidic nor basic. This balance is important for maintaining various biological and chemical processes.https://www.youtube.com/watch?v=31F0laJjyy8&t=276s
