Properties of Water

Question 1

Changes of Water

Answer 1

At 0 degrees Celsius water becomes a solid.
At 100 degrees Celsius water becomes a gas.

Question 2

Facts about particles

Answer 2

All particles are in constant, random motion.
The amount of movement a particle has is determined by the amount of energy it has.

Question 3

Fact about Molecules

Answer 3

As energy is transferred away from, or to these molecules, the state of matter may change.

Question 4

Particles in states of matter

Answer 4

All the particles in a solid, liquid, or gas are the same, what changes is the amount of energy.
Solid have a low amount of energy: vibrate.
Solids are incompressible. Amorphous solid
There is no free space.

Question 5

Facts about liquids and gases.

Answer 5

Liquids are incompressible. No free space
Gases have a lot of energy, move quickly, and can be compresses, because there is a lot of free space.

Question 6

H and O

Answer 6

The O = Negative (O‾)
The H = Positive (H+)
Unequal charge = Polar

Question 7

Formation of Hydrogen bonds in water

Answer 7

Water has a variety of unusual properties because of attraction between these polar molecules.
Hydrogen bonds are weak. Easy to make and break.
They are fickle = can’t make up their mind always looking for friends.

Question 8

Formation of Hydrogen bonds in water Part 2.

Answer 8

Hydrogen bonds exist between water molecules.
Weak Hydro 1/20th

Question 9

Fact about hydrogen bond

Answer 9

The slightly negative regions of one molecule are attracted to the slightly positive regions of nearby molecules, forming a hydrogen bond.

Question 10

How many water molecules can form hydrogen bonds.

Answer 10

Each water molecule can form a maximum of 4 hydrogen bonds.
The hydrogen bonds joining water molecules are weak, about 1/20th as strong as covalent bonds.

Question 11

Facts about water

Answer 11

68% of our bodies are made of water.
55% of our blood is water.
Water is involved in the creation of every organic compound.

Question 12

Results of Hydrogen Bonds.

Answer 12

Extraordinary Properties that are a result of hydrogen:
- Cohesive behavior
- Resist changes in temperature
- High heat of evaporation
- Expands when it freezes

Question 13

Water unique properties

Answer 13

Its unique properties are due in great part to hydrogen bonds and polarity.

Question 14

Barrel Wave

Answer 14

• Right Slope
• Moon Shape
• Wind
• Land Formation
