Water Properties

Multiple Choice

Water's unique properties plays a vital role in all living organisms including water's high specific heat, cohesion, adhesion, capillary action and being a universal solvent. This is due to which overall property of water?

• Water is cold which makes it polar and the covalent bonds that is between the water molecules.

• Water has a positive and negative charge and can form many hydrogen bonds

• Water is nonpolar which means it is hydrophobic and can form these special properties

• Water only have positive charges and molecules with positive charges must have special abilities.
