Intermolecular Forces and Phase Changes

Front

What happens to the energy of the system during the phase transition from liquid to gas?

Back

Energy is absorbed.

Front

How does increasing temperature affect the kinetic energy of particles in a substance?

Back

It increases the kinetic energy.

Front

Which phase change involves the release of energy?

Back

Condensation.

Front

How do stronger intermolecular forces affect the boiling point of a substance?

Back

Stronger intermolecular forces result in a higher boiling point.

Front

What is an example of a dipole-dipole interaction?

Back

The attraction between two polar molecules.

Front

Define intermolecular forces.

Back

Forces of attraction or repulsion between neighboring particles (atoms, molecules, or ions).

Front

What is vaporization?

Back

The phase transition from liquid to gas.

Front

What is condensation?

Back

The phase transition from gas to liquid.

Front

How do weaker intermolecular forces affect the boiling point of a substance?

Back

Weaker intermolecular forces result in a lower boiling point.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, kinetic energy increases.
