| Term | Definition |
|---|
| normal boiling point | the temperature at which the vapor pressure of a liquid is exactly one atm; the boiling temperature under one atm of pressure |
| healing/cooling curve | a plot of temperature vs time for a substance, where energy is added at a constant rate |
| normal freezing point | the melting/freezing point of a solid at a total pressure of one atm |
| intramolecular forces | interactures that occur within a given molecule |
| intermolecular forces | relatively weak interactions that occur between molecules |
| molar heat of fusion | the enrgy required to melt one mole of solid |
| molar heat of vaporization | the energy required to vaporize one mole of liquid |
| dipole-dipole interactions | the attractive force sulting when polar molecules line up such that the positive and negative ends are close to each other |
| hydrogen bonding | unusually strong dipole-dipole attractions that occur among molecules in which ydrogen is bonded to a hightly electronegative atom |
| london dipersion force | the relatively weak forces which exist among noble gas atoms and nonpolar molecules that involve momentary dipole that induces a momentary dipole in a neighbor. |
| vaporization | the change in state that occurs when a liquid evaporates to form a gas |
| condensation | the process by which vapor molecules re-form a liquid |
| vapor pressure | the pressure of the vapor over a liquid at equilibrium |
| crystalline solid | a solid characterized by the regular arrangement of its components |
| ionic solid | a solid containing cations and anions that dissolves in water to give a solution containing the separated ions which are mobile and thus free to contact an electric current |
| molecular solid | a solid composed of small molecules |
