weak intermolecular forces because dry ice with sublime
The intermolecular force that exists between Na and water is primarily ionic bonding. When Na is placed in water, the water molecules surround the Na ions and form hydration shells due to the attraction between the positively charged Na ions and the negatively charged oxygen atoms in water molecules.
The main intermolecular forces between water molecules are hydrogen bonds which are pretty strong as far as intermolecular forces go. Between hydrocarbon chains (oil) the main intermolecular force are London force which are weaker. For two liquids to be miscible the intermolecular forces between them have to be similar in strength or they won't dissolve. Water and oil have different strengths of intermolecular bonds so don't mix.
The intermolecular bonds between water molecules are hydrogen bonds.
intermolecular forces
Melting involve that intermolecular forces are weakened.
The strongest intermolecular force between two molecules of water in ice is hydrogen bonding.
Hydrogen bonds between molecules
Hydrogen bonds
This is an intermolecular attraction of water molecules, associated by hydrogen bonds.

Water (H2O) has stronger intermolecular forces than ammonia (NH3) due to hydrogen bonding in water molecules. Hydrogen bonding is a type of intermolecular force that is stronger than the dipole-dipole interactions present in ammonia molecules.

A water molecule is formed by two O-H bonds. Water molecules are attracted to each other by the intermolecular force; hydrogen bonding.

The main intermolecular force holding water molecules together in hydrogen bonding. Also, there are diplole-dipole interactions and London dispersion forces. But hydrogen bonds are the major force keeping water in the liquid state.
Water molecules have polar characteristics. They have strong intermolecular bonds, namely, hydrogen bonds. But the only intermolecular force present between petrol molecules is London forces which is relatively very weak than hydrogen bonding.
The electrostatic attraction known as hydrogen bonds that form directional intermolecular associations.
