Question

What is the physical state of the water at:
A》250°c
B》100°c

Answer 1

A >> for 250°C it is gaseous because the boiling poin of the water is 100°C.
B>> for 100°C it is in both gaseous and liquid because boiling point of water is    
         100°C so liquid is converting in to vepour so it is present in both state.
          vapour and liquid are in equilibrium in this temprature.

Answer 2

A>> At 250°C, the water remains in  vapour state or Gaseous state
B>> At 100°C, water remains as both liquid as well as gaseous state
