Water

Water is a polar molecule. Polar = unequal charges

The hydrogen bonds between water molecules give it special properties important to life.

1. Cohesion: water bonds to itself

2. Adhesion: water bonds to other substances

*Cohesion & adhesion help plants carry water up from the roots to the leaves*

3. High Specific Heat: it takes a lot of energy for water to heat up or cool down

* When it is hot outside our body does not heat up quickly or freeze when it is cold.

Universal Solvent: water dissolves many things

solvent: dissolves other substances

solute: a substance that gets dissolved

solution: mixture of solvent & solute

*water in blood dissolves nutrients to carry to all parts of your body
