6.1 Liquid State of Matter

Flashcards of vocabulary terms related to the liquid state of matter.

Adhesive Forces

Attractions between molecules of different substances.

Boiling Point

Temperature a liquid changes to a gas throughout the bulk liquid.

Capillary Action

Upward movement of a liquid in a narrow tube due to adhesion.

Cohesive Forces

Attractions between molecules of the same substance.

Condensation

Phase change from gas to liquid.

Definite Volume

Property of liquids and solids; occupy a fixed amount of space.

Density

Mass per unit volume.

Diffusion

Spontaneous mixing of particles due to random motion (high to low concentration).

Evaporation

Phase change from liquid to gas occurring at the surface below the boiling point.

Fluid

A substance that can flow (liquids and gases).

Freezing Point

Temperature at which a liquid changes to a solid.

Incompressible

Resists changes in volume when pressure is applied.

Indefinite Shape

Property of liquids and gases; take the shape of their container.

Intermolecular Forces (IMFs)

Attractive forces between molecules.

Kinetic Molecular Theory (KMT)

Model explaining matter's behavior based on particle motion.

Melting Point

Temperature at which a solid changes to a liquid (same as freezing point).

Meniscus

Curved surface of a liquid in a container.

Solubility

Ability of a solute to dissolve in a solvent.

Solute

Substance being dissolved.

Solvent

Substance doing the dissolving (usually the component present in larger amount).

Sublimation

Phase change directly from solid to gas.

Surface Tension

Energy required to increase the surface area of a liquid; tendency to minimize surface area.

Vapor Pressure

Pressure exerted by the vapor (gas) in equilibrium with its liquid phase.

Vaporization

Phase change from liquid to gas.

Viscosity

A liquid's resistance to flow.
