Water properties and solubility

Capillary action is the result of adhesion. Which aspect of water is responsible for this?

• Nonpolar covalent bonds that enable water to dissolve other substances
  
• Polar covalent bonds that join molecules of water to other substances
• Hydrogen bonds between water and another substance
• Ionic bonds that enable electrons to flow through water and into another substance

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.
