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.
