tendency of molecules of the same kind to stick to one another

• cohesion

• adhesion

• solution

• polar molecule

Attractions between water molecules are called

• Covalent bonds

• Ionic bonds

• Polar bonds

• Hydrogen bonds

What word describes when water is attracted to other substances?

• cohesion
• adhesion
• capillary action
• surface tension

Because the oxygen atom in a water molecule pulls stronger on the shared electrons...

• water is a polar molecule

• the hydrogen atoms cannot stay bonded

• water molecules are electrically neutral

• no electrons are safe

The tendency of water molecules to attract (stick to) other substances is called

• cohesion

• adhesion

• polarity

• specific heat

Attractions between water molecules are called

• Covalent bonds
• Ionic bonds
• Polar bonds
• Hydrogen bonds

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.
