Learning Objective
I can relate water's unique properties to its role in Earth's systems.
- 1
Water molecules are polar, with a slightly negative charge on the oxygen atom and slightly positive charges on the hydrogen atoms, leading to hydrogen bonds between water molecules.
- 2
Water's high cohesion due to hydrogen bonds results in high surface tension, allowing some insects to walk on water, while adhesion describes water's attraction to other substances like glass.
- 3
Water is an amazing solvent because its polarity allows it to dissolve more substances than any other liquid, and substances that dissolve in water are called hydrophilic, while those that don't are called hydrophobic.
