Volatile liquids are liquids with low boiling points and high
vapor pressure- in other words, they tend to evaporate more easily at room temperature.
Substances have different pressures in which they can maintain equilibrium between their liquid
and gas phases. The higher a liquid’s vapor pressure, the more volatile it
is.
Because of their low boiling points, volatile liquids convert to
the gas phase at a lower temperature and the gas molecules can diffuse faster than the molecules
of a non-volatile liquid. This is the reason why perfumes use volatile liquids so that their odor
can disperse more quickly into the air.
Some other examples of
volatile liquids include acetone, ammonia, dichloromethane, and
diethylether.
