Intermolecular forces
Water has a low boiling point because the forces between the molecules are weak. On the diagram, the forces between H and O are strong covalent bonds. It takes a lot of energy to break up water into H and O. However, it is easy to separate the molecules. In an exam answer, you need to make it clear that it is the inter-molecular forces that you are talking about.
