Which physical properties is not affected by an increase in intermolecular forces?
The correct answers are: Capillary attraction; Melting point; and Heat of vaporization. Stronger intermolecular forces increase capillary attraction, melting point, and the heat of vaporization. They have no bearing on conductivity and hardness.A.HardnessB.ConductivityC.Capillary attractionD.Melting pointE.Heat of vaporization
How melting and boiling points are affected by intermolecular forces?
Melting and boiling points are higher when intermolecular forces (such as hydrogen bonding, dipole-dipole interactions, or London dispersion forces) are stronger. These forces hold molecules together, so more energy is required to overcome them and change the state of the substance. Conversely, weaker intermolecular forces result in lower melting and boiling points.
What are inter particle forces of attraction?
Inter-particle force, also known intermolecular force, are forces of attraction and repulsion which act between neighboring particles. compared to intramolecular forces, they are a weak force.
What is an attraction between molecules of the same substance and why?
An attraction between molecules of the same substance is called cohesion. This occurs because molecules of the same substance have similar properties and are able to bond together through intermolecular forces such as hydrogen bonding or van der Waals forces. Cohesion is responsible for many properties of substances, such as surface tension in water.
What are the intermolecular forces of attraction within pentane?
The intermolecular forces in pentane are London dispersion forces. These forces result from the temporary uneven distribution of electrons in the molecule, leading to temporary dipoles. Due to the nonpolar nature of pentane, London dispersion forces are the predominant intermolecular forces present.
What can infer about the attraction between particles in a substance with a low melting point?
The stronger the intermolecular forces, the higher the boiling point, because more kinetic energy is needed to break these intermolecular forces apart.

What is the strongest of the intermolecular bonds?
Hydrogen bonds can be considered as the strongest intermolecular attraction forces.

These forces hold molecules together, so more energy is required to overcome them and change the state of the substance. Conversely, weaker intermolecular forces result in lower melting and boiling points.
Is there force of attraction between molecules of Atoms?
Yes, indeed. These forces are known as intermolecular forces. Molecular solids typically have weak van der Waals forces also known as weak intermolecular forces. Under certain conditions, these bonds can break allowing the element or substance to react.
What is it when atoms combine the force of attraction that holds the together?
Intermolecular forces
What kind of intermolecular forces does CO have?
Dipole-dipole attraction and van der Waals forces.

Are intermolecular forces of attraction strong?
the strength depends on the molecule in question, but they are strong

Due to the nonpolar nature of pentane, London dispersion forces are the predominant intermolecular forces present.
What is the relationship between intermolecular forces and vaporization points?
The greater the potential of a liquid's molecules to interact with each other through intermolecular forces, the lower the vapour pressure is going to be above the liquid (because molecules will preferentially stay liquid and interact with other molecules rather than fly away as a gas), and the lower the boiling point of the liquid. Therefore the relationship is an inverse one.
