How do intermolecular forces of methane and water explain the different boiling points of the two substances?

Explanation:

In methane the intermolecular forces are the weak London dispersion forces. Water molecules are held together by hydrogen bonding.

London dispersion forces are weak forces of attraction between molecules. It is a predominant in compounds that have very weak polarity.Hydrogen bonding is the electrostatic attraction between the hydrogen of one molecule and the electronegative atom(O or N or F) of a neighboring molecule.

Hydrogen bonds holds water molecules together. Since it is a stronger bond, it confers a higher boiling point

North atlantic current or north atlantic drift is the answer

The closer the atoms are to becoming ionic the more highly dense the negatively charged side gets.
