1

How much of the earth's surface is covered in water

70%

2

Where is the majority of the water of earth stored

the ocean

3

What percentage of water is available for humans to consume

3%

4

How is the structure of a water molecule related to unique properties

Water’s structure is what creates all of it’s unique properties.

5

What is a water molcules covalent bond

H-O
I
H

6

Hyrdrogen bonding between water molecules

Draw a big circle with an O in it with a - and draw two smaller circles around the O and put the letter H in them. Then, put a + next to it.

7

Oppositely charged regions

Polarity

8

slight negative

Oxyegn

9

slight positive

Hydrogen

10

attraction between the slightly positive end and slightly negative end of different molecules.

Hydrogen bonding

11

an attraction between molecules of the same substance.

Cohesion

12

Is the caused by cohesion between water molecules along the surface.
Makes the water act like there is an elastic membrane across the surface

Surface Tension

13

an attraction between molecules of different substances.

Adhesion

14

Water is very ________

cohesive

15

Water travels against the
direction of gravity through
the process of adhesion to
the walls of it’s “container”.

Capilary action

16

_________ is stronger then cohesion

adhesion

17

Water’s ______ allows it to dissolve more substances than any other liquid!!

polarity

18

Amount of heat it takes to raise the temperature of 1 gram of a substance 1 degree celsius.

specific heat

19

Waters specific heat is very

high

20

Why is waters specific heat important for all forms of life

Aquatic animals don’t have to worry about their homes heating up too fast and killing them and Human bodies are about 75% water. Our body temperatures don’t fluctuate very fast! If they did….we would die!

21

How can water travel against gravity

capilary action

22

What property of water makes a surface tension

Cohesion

23

Water falling as raindrops is an example of

cohesion

24

capilary action is anexample of

adhesion and cohesion

25

water regulating the earths temperature is an example of

specific heat

26

Paper towels attract water

adhesion

27

Why does water have so many unique properties

Polar covalent bonds
