Question

what is the physical state of water at 250 degree Celsius and hundred degree Celsius

Answer 1

a) at 250 degree celsius: Gaseous state.

B) at 100 degree celsius: liquid as well as gaseous state.

Answer 2

Water exists in Vapour state (steam) at 250°C

At 100°C, (which is the temperature at which water starts to boil) there exists an Equilibrium between the liquid and vapour state of water, thus we find that water exists as both liquid as well as gas at 100°C
