The escape speed from the Moon is much smaller than from Earth and is only 2.38 km/s. At what temperature would neon atoms (with an atomic mass equal to 20.18 g/mol) have an average speed vrms equal to the Moon's escape speed

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
