naked eye
Condensation process of gas being converted to liquid
the temperature above which a substance cannot
Critical point

Why are liquids the least they can exist only within a relatively narrow range of
common state of matter? temperatures and pressures
Vaporization is the conversion of liquid particles to
vapor at the boiling point temperature of the material.
Differentiate between
The process of liquid converting to vapor molecules
