  Vapor  \Va"por\,  n.  [OE.  vapour,  OF  vapour,  vapor,  vapeur,  F. 
  vapeur,  L.  vapor;  probably  for  cvapor,  and  akin  to  Gr  ? 
  smoke,  ?  to  breathe  forth,  Lith.  kvepti  to  breathe,  smell, 
  Russ.  kopote  fine  soot.  Cf  {Vapid}.]  [Written  also 
  {vapour}.] 
  1.  (Physics)  Any  substance  in  the  gaseous,  or  a["e]riform, 
  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 
  called  steam. 
 
  Vapor  is  any  substance  in  the  gaseous  condition 
  at  the  maximum  of  density  consistent  with  that 
  condition.  This  is  the  strict  and  proper  meaning 
  of  the  word  vapor.  --Nichol. 
 
  2.  In  a  loose  and  popular  sense  any  visible  diffused 
  substance  floating  in  the  atmosphere  and  impairing  its 
  transparency,  as  smoke,  fog,  etc

  4.  Something  unsubstantial,  fleeting,  or  transitory;  unreal 
  fancy;  vain  imagination;  idle  talk;  boasting.

  vapors  as  compared  with  some  specific  standard,  usually 
  hydrogen,  but  sometimes  air.  The  vapor  density  of  gases 
  and  vaporizable  substances  as  compared  with  hydrogen,  when 
  multiplied  by  two  or  when  compared  with  air  and 
  multiplied  by  28.8,  gives  the  molecular  weight.
