Properties of Liquids Flashcards
the measure of the elastic force in the surface of a liquid.
Liquids that have this have high IMF.
Surface Tension
between the molecules in the liquid
Cohesive Forces
between the molecules and the surface of another substance
Adhesive Forces
rise of liquid up narrow tubes and results from the competition between the cohesive forces and the adhesive forces.
Capillary Action
the measure of a liquid’s resistance to flow. The higher this has, the higher the IMF but the lower the temperture.
Viscosity
gas phase above a substance that exists as solid or liquid at 25’C and 1 atm
Vapor/Vapor Pressure
Number of molecules that go into the gaseous state is equal to?
Number of molecules that condense back
Rate of condensation is equal to?
Rate of evaporation
The gas in the containter is in _____ with the liquid.
Equilibrium
In this case, Vapor pressure is independent of volume of the containter
Dynamic Equilibrium
pressure exerted by the gas in equilibrium with a liquid in a closed container at a given temperature.
the maximum vapor pressure of a liquid at a given temperature
the higher the nunber of gaseous particles, the higher the pressure
Equilibrium Vapor Pressure
relation of pressure and IMF
inversely proportional
liquids with low Vapor Pressure have strong what?
London Dispersion Forces and dipole-dipole forces
The relation of IMF to amount of energy needed to break them?
Directly Proportional
the energy required to vaporize 1 mole of a liquid at a given temperature
the higher, intermolecular attraction = the higher, energy is required to free the molecules from liquid phase
Molar Heat of Vaporization
