Intermolecular Forces

forces within a molecule

Viscosity

resistance to flow

Molar heat of vapoization

heat required to vaporize 1 mol of liquid at a constant pressure

Molar heat of fusion

heat released when 1 mol of liquid solidifies

Boiling Point

Temperature at which vapor pressure becomes equal to atmospheric pressure

Normal boiling point

Temperature at which a liquid boils at standard pressure (1 atm)

Melting point

temperature at which solids turn into liquids

Solution

Composition and physical and chemical properties are identical throughout

Solute

Substance being dissolved

Solvent

Substance doing the dissolving

Soluble

When a substance dissolves to an appreciable quantity

Miscrible

Two substances that can be mixed in all proportions

Insoluable

When very little, almost none, of a substance dissolves

Saturated

Solution that contains all the solute that it can at equilibrium

Unsaturated

Solution that contains less than this quantity

Supersaturated

Solution containing solute in excess of what it could contain if it were at equilibrium

Molarity

Amount of solute in moles per liter of solution

Aqueous

containing water, typically as a solvent

Hydrate

compounds in crystallized form with bound water molecules

Anhydrous

compound without water

Efflorescent

hydrates that lose their water to air

Hygroscopic

hydrates that pick up water from air

Deliquescent

compounds so good at pulling water molecules from air that they eventually dissolve into water
