Properties of Water Review

What is the charge on the oxygen atom?

• Positive

• Negative

Water has a slightly positive end AND a slightly negative end, this means water has

• polarity

• cohesion

• adhesion

• specific heat

What two elements make up water?

• Helium and oxygen
• Hydrogen and oxygen
• helium and carbon
• oxygen and carbon

Water is a universal solvent because it...

• It can be found anywhere
• It freezes when it gets cold
• floats when frozen
• Dissolves most substances

Surface tension is caused by ...

• strong cohesion between water molecules
• strong adhesion between the water molecules
• condensation
• water cycle

Refer to the picture; this is occurring due to:

• Adhesion
• Cohesion

Describe ADHESION.

• Water molecules attracted to other substances.

• Water molecules climbing upwards against the force of gravity.

• Water molecules dissolving many substances because of its polarity.

• Water molecules attracted to other water molecules.

Paper clips are able to float on water because of ....

• adhesion
• capillary action
• surface tension
• universal solvent

Describe COHESION.

• Water molecules attracted to other substances.

• Water molecules climbing upwards against the force of gravity.

• Water molecules dissolving many substances because of its polarity.

• Water molecules attracted to other water molecules.

Why does water move from the roots to the leaves of plants?

• Water is pushed by solutes
• Capillary action pulls the water molecules like a chain
• Water is pulled by gravity
• Water’s cohesion causes it to “pull” towards the leaves
