Properties of Water

Water is polar because...

• The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.
• The molecule has two poles, at which the it is colder than other regions of the molecule.
• The unequal sharing of electrons gives the water molecule a slight negative charge near its hydrogen atoms and a slight positive charge near its oxygen atom.
• The water molecule is neutral.

What property of water helps to moderate earth's temperature?

• adhesion
• cohesion
• specific heat capacity
• pH

The attraction that causes water and other liquids to form drops on thin films is called ________________. This is also water’s ability to be attraction to other water molecules.

• adhesion
• capillary action
• cohesion
• surface tension

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.

What term describes when water is attracted to other substances?

• Cohesion
• Adhesion
• Capillary Action
• Surface Tension

What term describes when water is attracted to other substances?

• Cohesion
• Adhesion
• Capillary Action
• Surface Tension

Why can water have no net charge but have slight charges in different parts of the molecule?

• The oxygen end is slightly negative and the hydrogen end is slightly positive.
• The hydrogen end is slightly negative and the oxygen end is slightly positive.
• The hydrogen and oxygen ends change in polarity.
• Because it is hydrophobic.

What word describes when water is attracted to other substances?

• cohesion
• adhesion
• capillary action
• surface tension

What produces surface tension?

• Water.
• Hydrogen bonds.
• Adhesion.
• Cohesion.

Water is a universal solvent because it...

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