about water

1. WATER

2. H2O

3. OBJECTIVE;
You should be able to describe the properties of
water that make it a molecule suitable for
supporting life.

4. WATER
Has immeasurable importance in
the lives of organisms , such that a
shortage of it is a threat to the
survival of species .

5. Cells of living organisms
are composed of approximately 70 to
90 percent of water.

6. Bodies of water
Rivers Lakes Seas

7. The Properties of
water
 High heat of vaporization
 High specific heat
 High ionizing power
 High surface tension
 Water expand

8. High heat of
vaporization
 it is the amount of
energy required to
vaporize one gram of
liquid.

9. High specific
heat
 which means
that water does
not easily boil .

10. High ionizing
power
 water has a slight
tendency to fall
apart (dissociate)
into hydrogen ions
(H+) and hydroxide
ions (OH-) , thus
making it an
excellent solvent .

11. High surface
tension
 the tendency of
molecules at the
surface of a liquid
to cohere to each
other and not to
the air above.

12. Water expands
 a special
property to
expand from 4
to 5 Celsius.
