Water - 3 molecules
2 hydrogen, each with delta plus charge and 1 oxygen with delta minus charge.
Charges attract H20 molecules to each other = hydrogen bonds
electron sharing bonds = covalent bonds
In ice - hydrogen bonds hold water molecules in a rigid lattice formation.
Solids - molecules vibrate, do not move around
Liquids - molecules have more kinetic energy, moving past each other -- forming fleeting hydrogen bonds with each other.
Gas (water vapour) - molecules far apart, scarcely interacting with eachother
Water - liquid @ normal temperature
- high specific heat capacity
- relatively high boiling point
- cohesion between water molecules
