Properties of Water

What is adhesion?

• Water is attracted to itself

• Water is attracted to other things

• Water is able to have surface tension

• Cold water is more dense than warm water

Why is does ice float instead of sinking?

• Because water becomes less dense as it becomes solid

• Because water becomes more dense as it becomes solid

• Because ice is lighter than the water

• Because ice has less mass than water

What is cohesion?

• Water is attracted to itself

• Water is attracted to other things

• An uneven distribution of electrons that cause partial positive and partial negative charges.

• Organisms maintaining equilibrium in the body

What is a hydrogen bond?

• Two molecules with polarity are attracted to each other

• Two molecules with no polarity are attracted to each other

• A bond between two atoms that creates water tension

• How water is able to dissolve non polar things

Which of these are examples of adhesion?

• Water is the universal solvent and excellent at dissolving things.Water sticking to you when it rains.

• Water on the penny in a bubble. Water on the wax paper. Water from the string to the beaker

• The ability of a substance to gain and lose heat energy

• Polarity

What is polarity?

• An uneven distribution of electrons that cause partial positive and partial negative charges within a molecule.

• An even distribution of electrons that causes no partial positives or partial negative charges within a molecule.

What is density?

• Mass/Volume. How close particles are.

• Volume/Mass. How far apart particles are.

• Mass x Volume. How close particles are.

• Mass x Volume. How far apart particles are.

These are examples of what property of water?

1. Water on the penny in a bubble

2. Water on the wax paper

3. Water from the string to the beaker

• Adhesion

• Cohesion

Heat capacity is the ability of a substance to gain and lose head energy. How does this help organisms to maintain homeostasis?

• The temperature can't change in living organisms, which makes it so that organisms live at the right temperature.

• The temperature takes longer to change than other liquids, and that helps the body hold onto the temperature.

• The temperature is able to rise quickly and lower quickly. This keeps things stable within the organism.

• The temperature is able to rise very slowly and lower slowly. This makes it so that organisms don't change their temperature.

What is a solvent?

• The things that dissolves other things

• The thing being dissolved

• The mixed solution

• The universal dissolver
