(a) Physical state of water at 250°C is gaseous state because the boiling point of water is 100°C. Therefore at a temperature higher than its boiling point, it exists as gas.
(b) At 100°C both liquid and gaseous states are present. These are in a state of equilibrium. So, at 100°C both liquid water and vapours are present.
