What is electron affinity?
acquired by a neutral atom
Held together by an extended network of covalent
Covalent network solids
bonds.
- freezing point depression

An azeotrope is a mixture of two or more liquids in
such a way that it cannot be altered by simple
What is an azeotrope?
distillation alone. (constant boiling mixtures no
change on boiling)
What is volatile? Easily evaporated at normal temperatures.
the temperature and pressure at which the solid,
What is the triple point? liquid, and vapor phases of a pure substance can
coexist in equilibrium.
