12 Terms

1

Intermolecular Forces

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

New cards
2

Kinetic Energy (KE)

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

New cards
3

Dipole-Dipole Attractions

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

New cards
4

Hydrogen Bonding

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

New cards
5

Dispersion Forces

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

New cards
6

Viscosity

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

New cards
7

Surface Tension

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

New cards
8

Capillary Action

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

New cards
9

Solubility

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

New cards
10

Saturated Solution

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

New cards
11

Supersaturated Solution

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

New cards
12

Surfactants

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