Boiling point of water at normal atmospheric pressure of 1 bar or 1 atm  is 100 deg C.

Freezing point of water  at normal atmospheric pressure is 0 deg. C

Hence,  water exists as liquid  between  0 deg C  and 100 deg C.

Physical state of water at 250 deg C  =  Vapour  or  gaseous state or steam..

Physical state of water at  100 deg C  =  either as water boiling  or  water vapour
   At 100 deg C,  at normal pressure ,  liquid water exists in equilibrium with water vapour.  So both states exist.
