Intermolecular Forces

Attractive forces between atoms, molecules, or ions that determine the physical properties of solids, liquids, and gases.

Kinetic Energy (KE)

The energy associated with the motion of molecules; influences the state of matter depending on the balance with intermolecular forces.

Dipole-Dipole Attractions

The electrostatic attraction between the positive end of one polar molecule and the negative end of another.

Hydrogen Bonding

A strong type of dipole-dipole attraction that occurs when hydrogen is bonded to highly electronegative atoms (like oxygen, nitrogen, or fluorine).

Dispersion Forces

Weak electrostatic attractions that result from temporary dipoles formed due to the constant motion of electrons in atoms or molecules.

Viscosity

A measure of a liquid's resistance to flow, often influenced by intermolecular forces and molecular complexity.

Surface Tension

The energy required to increase the surface area of a liquid, arising from cohesive forces between molecules at the surface.

Capillary Action

The spontaneous rising of a liquid in narrow spaces between solid surfaces due to cohesive and adhesive forces.

Solubility

The maximum amount of solute that can dissolve in a given quantity of solvent at a specific temperature to form a saturated solution.

Saturated Solution

A solution that contains the maximum amount of dissolved solute at a given temperature.

Supersaturated Solution

A solution that contains more dissolved solute than what is normally possible at a given temperature.

Surfactants

Substances that decrease surface tension by absorbing to interfaces, often containing both polar and nonpolar portions.
