HELP WILL GIVE MEDAL AND FAN!!! What is the best explanation for the observation that H2O is a liquid at room temperature and H2S is a gas at room temperature? The average kinetic energy of the H2O particles is lower than that of the H2S particles. The intermolecular forces in H2O are stronger than those in H2S. The boiling point of oxygen gas is lower than that of sulfur. The molecular mass of H2O is lower than that of H2S.

The intermolecular forces in H2O are much stronger than H2S hydrogen bonding in water
