What is the intermolecular force of Ar?
The intermolecular force in Ar (argon) is London dispersion forces, which are the weakest type of intermolecular force. This force is caused by temporary fluctuations in electron distribution around the atom, leading to temporary dipoles.
What is the force needed to overcome intermolecular attractions and break through the surface of a liquid or spread out of the liquid?
surface tention
What fluid force opposes motion?
Both the friction between the moving body and the liquid, and between the molecules of the liquid. And other intermolecular forces the keep the liquid together (like Van-der-Waal force)
What intermolecular force must be overcome to boil liquid n2?
To boil liquid nitrogen (N2), the intermolecular force that must be overcome is the London dispersion forces. These are weak forces that arise from temporary fluctuations in electron density, leading to temporary dipoles. Although these forces are relatively weak compared to other intermolecular interactions, sufficient energy must be provided (in the form of heat) to break these interactions and transition nitrogen from a liquid to a gaseous state.
Why do molecules at the surface of a liquid behave differently from molecules in the interior of the liquid?
In the interior the intermolecular forces of attraction is equal in all directions but the molecules at the surface of liquid experiences unequal intermolecular forces of attraction. the molecules at the surface are free so the adsorb liquid or gaseous molecules
What is the intermolecular force of Ar?

What is the dominant intermolecular force between Na plus to Ar?
ion to dipole
Does the boiling point of a liquid decreases increases or stay the same if the intermolecular force increases?
Generally, the boiling point of a liquid increases if the intermolecular force, i.e. pressure, increases.
What is the intermolecular force between BF3 in liquid state?
The intermolecular force between BF3 molecules in liquid state is London dispersion forces. This is because BF3 is a nonpolar molecule and London dispersion forces are the primary intermolecular force among nonpolar molecules.
Which intermolecular force is most important in allowing Ar gas to liquefy?
Van der Waals forces, specifically London dispersion forces, are the most important intermolecular forces that allow Ar gas to liquefy. These forces arise due to temporary dipoles induced in Ar atoms leading to attractive forces between neighboring atoms. At low temperatures and high pressures, these forces prevail, causing Ar gas to condense into a liquid state.
What is the force needed to overcome intermolecular attractions and break through the surface of a liquid or spread out of the liquid?
surface tention
Does intermolecular force change from solid to liquid or liquid to gas?
Yes, the intermolecular forces generally change as a substance transitions from solid to liquid to gas. In solid form, molecules are held together by strong intermolecular forces. In liquid form, these forces weaken to allow molecules to move more freely. In gas form, intermolecular forces are weakest as molecules are far apart and move independently.
What fluid force opposes motion?
Both the friction between the moving body and the liquid, and between the molecules of the liquid. And other intermolecular forces the keep the liquid together (like Van-der-Waal force)
Is the force of attraction stronger in the molecules of a solid or liquid?
The force of attraction is generally stronger in the molecules of a solid compared to a liquid. In a solid, the molecules are closely packed and have limited movement, allowing for stronger intermolecular forces to hold them together. In a liquid, the molecules have more freedom to move, resulting in weaker intermolecular forces.
What intermolecular force must be overcome to boil liquid n2?
To boil liquid nitrogen (N2), the intermolecular force that must be overcome is the London dispersion forces. These are weak forces that arise from temporary fluctuations in electron density, leading to temporary dipoles. Although these forces are relatively weak compared to other intermolecular interactions, sufficient energy must be provided (in the form of heat) to break these interactions and transition nitrogen from a liquid to a gaseous state.
How are the molecules in a particular solid different from the molecules of that substance in a liquid form?
the molecules in solids are tigthly packed that is the intermolecular force(cohesive) force is more but in liquids the intermolecular force(cohesive force) is less .solids have fixed shape,volume, mass but liquids have no fixed shape as it takes shape of the container.
What happens if intermolecular force increase?
If intermolecular forces increase, the attractions between molecules will strengthen. This can lead to molecules forming more stable structures, such as a solid from a liquid, or a liquid from a gas. It can also result in higher boiling and melting points for substances.
