1. (Physics) Any substance in the gaseous, or aeriform,
state, the condition of which is ordinarily that of a
liquid or solid.
Note: The term vapor is sometimes used in a more extended
sense, as identical with gas; and the difference
between the two is not so much one of kind as of
degree, the latter being applied to all permanently
elastic fluids except atmospheric air, the former to
those elastic fluids which lose that condition at
ordinary temperatures. The atmosphere contains more or
less vapor of water, a portion of which, on a reduction
of temperature, becomes condensed into liquid water in
the form of rain or dew. The vapor of water produced by
boiling, especially in its economic relations, is

at the maximum of density consistent with that
