WATER

WHAT IS THE DENSITY OF WATER?

WATER STATES OF MATTER WITH THEIR TEMPERATURES

• Solid (ice) 0 degrees Celsius (32 degrees f.)
• Liquid (regular water
• Gas (vapor or steam) 100 degrees Celsius (212 degrees f.)

WHEN WATER GOES FROM SOLID TO GAS (SKIPPING LIQUID PHASE)

Water is polar because of the difference in electronegativity between hydrogen and oxygen. The highly electronegative oxygen atom attracts electrons or negative energy to it, making the region around the oxygen more negative than the areas around the two hydrogen atoms.
However, the molecule would not be pole if h2o was linear like, for example, carbon dioxide, co2. Each water molecule is bent so that the positive portions of the molecule (the hydrogen atoms) re flexed away from the two filled orbitals of the atoms.

WHAT DOES COHESION OF WATER MEAN

WHAT DOES ADHESION OF WATER MEAN

WHY IS WATER CALLED THE UNIVERSAL SOLVENT

• Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. It dissolves more substances than any other liquids.

Solvent- the liquid in which a solute is dissolved in to form a solution.
Solute- the minor component in a solution, dissolved in the solvent.

Solid (ice)- no movement or extremely slow.
Liquid (regular water)- movement, but stays in its given container.
Gas (vapor or steam)- fast, random movement not confined to its set container.
