Hydrogen (+) Positive H Hydrogen (+) Positive H Oxygen (-) Negative O Water Molecule

Properties of Water Water is a polar molecule. It has a (+) positive and a (-) negative end. As a result each water molecule is like a little magnet. This property causes water molecules to be very attracted to each other.

The Universal Solvent Capable of dissolving a variety of substance Able to do this because of polar property This allows the water molecule to become attracted to many other different types of molecules.

Dissolving Salt Water can become so heavily attracted to a different molecule, like salt (NaCl), that it can disrupt the attractive forces that hold the sodium and chloride in the salt molecule together and, thus, dissolve it

Specific Heat Capacity Means amount of heat needed to raise the temperature of water to a certain amount. Water has a low specific heat meaning it takes a lot of heat to make it hot

How does that benefit life? Helps us maintain our body temperature Fish are not dying because the temperature of water is able to stay somewhat the same from day to night Regulates the temperature in the atmosphere

Bonding of Water A Hydrogen bond holds them together. This type of bond is a relatively weak force of attraction between an H atom and the negatively charged atom of another molecule. These bonds create 2 types of attractive forces: Cohesion and Adhesion

Properties of Water Cohesion: attraction between like molecules Example: Surface Tension, beads of water Adhesion: attraction of different molecules Example: Capillary Action
