physical properties of solvents that are dependent on the concentration of the solute
present and the identity of the solvent but not on the identity of the solute. They include
vapor pressure, freezing point and boiling point
Colloids
heterogeneous mixtures which appear to homogeneous one-phase mixtures but are
actually composed of particles too small to be seen with the naked eye
Condensation
process of gas being converted to liquid
Critical point
the temperature above which a substance cannot exist in the liquid phase
Critical pressure
the lowest pressure required for the substance to exist as a liquid at the critical point
Crystalline solids
particles are arranged in one of several different orderly, repeating, geometric patterns
, Electrolytes
ionic or very polar compounds which dissolve to form solutions of ions which conduct an
electric current
Fluids
substances like liquids and gases which have no fixed shape and so they flow
Ionization
the splitting of molecules to form ions
Molality
the number of moles of solute present per kilogram of solvent
Molarity
the number of moles of solute present per liter of solution
Nonelectrolytes
compounds which dissolve to form solutions of molecules which do not conduct an
electric current
Phase
any state of matter such as solid, liquid or gas
Strong electrolytes
solutes that ionize completely
Sublimation
the conversion of a solid directly to the gas state
Surface tension
