The electromagnetic attraction of the atoms or molecules.
Don't use Emma's answer if this is for school, schools tell you to disregard it in these cases, since it is such an insignificant contributor.
No offense Emma.

The forces that must be overcome when water boils are the intermolecular attractions between water molecules. These are, in order of importance:
H-bonding
dispersion forces
Notes:
1) H-bonding is of the order of 100 x stronger than dispersion forces.
2) H-bonding is of the order of 1/10 as strong as the covalent bonds holding the water molecule together.

Hydrogen bonds
Dipole-dipole since the water molecule is polar
Van der Waals dispersion forces. Their contribution is very small compared to the previous two types of forces but still they are overcome when water boils.
