Fuerza intermolecular

The video explains that intermolecular forces are weaker than chemical bonds, which hold atoms together in molecules. These forces arise from irregular electron distributions and are stronger in solids than in liquids, decreasing when substances melt or boil.

What is the relationship between intermolecular forces and chemical bonds within molecules?

• Intermolecular forces are stronger than chemical bonds.

• Intermolecular forces are weaker than chemical bonds.

• Intermolecular forces do not exist within molecules.

• Intermolecular forces and chemical bonds have the same strength.

What causes intermolecular forces to arise?

• Irregular distributions of electrons.

• Regular distributions of protons.

• Regular distributions of neutrons.

• Irregular distributions of protons.

How do intermolecular forces compare in solids and liquids?

• They are stronger in liquids than in solids.

• They are weaker in solids than in liquids.

• They are the same in both solids and liquids.

• They are stronger in solids than in liquids.

What happens to intermolecular forces when a substance is melted?

• They remain unchanged.

• They increase.

• They decrease.

• They disappear completely.

What happens to intermolecular forces when a substance is boiled?

• They decrease.

• They remain unchanged.

• They increase.

• They disappear completely.
