What are the weakest attraction between molecules?
London dispersion is the weakest interatomic force. It relies on the motion of electrons to form a momentary (temporary) multipole in one atom, and induce a momentary multipole on nearby atoms. It is extremely distance sensitive (the energy of the attraction is inversely proportional to the distance between the particles to the sixth power) and is the weakest attractive force in most circumstances. Despite its apparent weakness, London dispersion can be powerful when occurring in large numbers and/or at very small radii. For example, Tokay Gecko feet have many very small protrusions sticking out of them that cause London dispersion interactions between them and the surface. This allows geckos to climb up nearly any surface at any angle.
Is phosphorus trichloride a liquid at room temperature?
PCl3 is a liquid at room temperature because, despite its very weak polarity, it has enough electrons present per molecule to cause numerous "dispersion forces," which are weak, temporary dipole moments which cause a measure of attraction between PCl3 molecules. This holds the substance together as a liquid.
Why are the forces that hold atoms together in molecules stronger than the forces that hold the molecules together in a gas?
Molecules are two or more atoms held together by a covalent bond. This is a very strong bond as it is held together by strong electrostatic charges. All covalent molecules (apart from those held together in a covalent lattice such as Diamond) are bonded to other molecules by Van der Waal forces. Its is these intermolecular bonds that control boiling and melting points. Van der Waals are (in this case) the attractive force between molecules, they are temporary bonds between temporary dipoles and as electrons orbit the nuclei of atoms the position changes. This temporary dipole induces other molecules to form induced dipoles. Strength varies due to shape of molecule (the more "oblong" the greater the strength of the bond) and by size (the greater the size the greater the strength of the bond.)
What is the difference between dispersion forces and dipole- dipole forces?
Dispersion forces are formed between two non-polar molecules. These molecules form temporary dipoles. This creates a weak force. Dipole Dipole forces have a permanent dipole. That is the basic explanation
Are there differences between covalent bonding and covalent compound?
Covalent compounds and molecular compounds are the same thing if I recalled correctly, just different terms of calling it. And covalent bonds are the bonds formed by the sharing of electrons between two atoms, and they are the strong forces of attraction WITHIN the molecule.Please do not get it mixed up with the weak van der Waals' forces that is found BETWEEN molecules and is caused by a temporary shift of electrons to one side of the molecule, resulting in a slightly positive/negative end.

What is the site and temporary storage area for newly synthesized molecules?
Rough ER (Endoplasmic Reticulum)
Is The Wizarding World of Harry Potter at Universal Orlando Resort a permanent attraction or just temporary?
Permanent but they might eventually change it.
How do van der Wals forces hold molecules together?
When molecules are close together, a slight attraction can develop between the oppositely charged regions of nearby molecules. Apex------They form temporary, weak dipole attractions between molecules.
How is a Van Der Waals force formed?
These bonds have an approximate energy of 0.5-1.0 kcal/mol. see related link

What molecule has an overall dipole moment?
All polar molecules have a permanent dipole moment, but London dispersion forces in non-polar molecules can cause temporary dipole moments as well.
