Front

Define intermolecular forces.

Back

Forces that occur between molecules, affecting their physical properties.

Front

What is the boiling point indicative of in terms of intermolecular forces?

Back

Higher boiling points generally indicate stronger intermolecular forces.

Front

What are the three main types of intermolecular forces?

Back

Dipole-dipole, hydrogen bonds, and dispersion forces.

Front

Explain hydrogen bonding.

Back

A strong type of dipole-dipole interaction that occurs when hydrogen is bonded to highly electronegative atoms like N, O, or F.

Front

What is absolute zero?

Back

The theoretical temperature at which a system has minimal energy, defined as 0 Kelvin.
