|
polarity
|
water is made of only two elements
|
|
|
Hydrogen bonds
|
are weak bonds between oxygen of one molecule and a hydrogen of a different molecule
|
|
|
universal solvent
|
water can dissolve more substance than anything else
|
|
|
cohesion
|
refers to water molecules sticking to other water molecules
|
|
|
capillary action
|
and cohesion are vital to the ability of plant to go through photosynthesis and sustain life
|
|
|
adhesion
|
water molecules ability to stick to other substances (that aren't water)
|
|
|
surface tension
|
allows materials to float on top of the water
|
|
|
high specific heat capacity
|
water is a great insulator and resists temp change
|
|
|
ice frozen
|
it expands and becomes less dense
|
|

organic compounds
|
all contain carbon and are less dense
|
|
|
carbon
|
is important because it will form 4 bonds to become stable
