Chap. 11 Intermoleculer Fource Flashcards
Intramolecular force
Force between atoms within a partial
Intermolecular force
Force between two molecules
Hydrogen bonds take place with
Nitrogen ,oxygen , and Florine
Viscosity
Measure of the fluids resistance to movement
Service tension
The measure of elastic forces within the surface of a liquid
Created by the side ways and downwards forces exerted on the molecules on the surface of a liquid
Vapor pressure
Pressure exerted on a liquid by the molecules that have escaped the liquid phase to gas phase
Higher the vapor pressure the lower the boiling point
Unit cell
Basic repeating structural unit of a crystalline solid
Lattic point
Corner point or connection point of molecules in a lattice structure
Types of unit cells
Simple cubic, tetragonal, orthorhombic, rhombohedral, monoclinic, triclinic, hexagonal,
Types of cubic cells
Simple , body centered, face centered
Simple cubic radius equation
a=2r
Body centered radius equation
a=4r/squrt(3)
Face centered radius equation
a=squrt(8)r
Brag equation
Wave length = 2dsin(thata)
Clausius- Clapeyron equation
ln(P) = -(delta H/RT) + C
ln(P1/P2) = delta H/ R( (1/T1) (1/T2) )
Latent heat
Heat absorbed by a substance while in the process of changing phase
Heat of fusion
Temp at which solid becomes liquid
Heat of vaporization
Temp at which liquid becomes gass
Heat of sublimation
Temp at which solid becomes gas
