Which sentence best explains the high melting point, boiling point, and surface tension of water? a. the hydrogen atom on each water molecule is strongly attracted to the hydrogen atoms on nearby molecules. b. ions dissolved in the water cause nearby molecules to become temporarily polar. c. the water molecules are connected to each other with covalent bonds. d. water molecules that have lost electrons attract the water molecules that have gained electrons. e. the negative side of each water molecule is attracted to the positive sides of nearby molecules.

E. The negative side of each water molecule is attracted to the positive sides of nearby molecules.

Explanation: The high melting point, boiling point, and surface tension of water is due to the strong inter molecular forces of attraction present between the water molecules.

The molecules are bonded through hydrogen bonding which arises due to polarity which is developed due to electronegativity difference between hydrogen and oxygen atoms.

Oxygen being more electronegative develops negative charge and hydrogen acquires positive charge, which leads to special kind of dipole dipole forces called as hydrogen bonds.
