AP Chemistry Intermolecular Forces

What is it called when a solid turns directly into a gas?

• Sublimation

• Condensation

• Liquid

Answer explanation

A solid turning into a gas is known as sublimation. An example of this includes dry ice turning into CO2.

Change from gas to liquid...

• condensation

• evaporation

• expansion

• movement

Answer explanation

When a substance changes from a gas to a liquid, it is known as condensation. An example of this is vapor condensing into water droplets on the side of a cold glass.

Which of the following best describes a dipole-dipole interaction?

• A force between two nonpolar molecules

• A force between a polar molecule and a nonpolar molecule

• A force between two polar molecules

• A force between two ions

What is the main difference between intermolecular and intramolecular forces?

• Intermolecular forces occur within a molecule, while intramolecular forces occur between molecules.

• Intermolecular forces occur between molecules, while intramolecular forces occur within a molecule.

• Intermolecular forces are stronger than intramolecular forces.

• Intermolecular forces are only found in gases.
