Hint:To solve this question, first we have to understand what it means by the term physical state. Physical state means the condition in which the matter exists under a specific condition and in this question the temperature is mentioned.

We know that the boiling point of water is 100 degree centigrade and after that water exists in gaseous states. It means that at 250$^{0}C$ water will exist in a gaseous state as water changes into vapours and boiling occurs.
Hence, the physical state of water at 250 $^{0}C$ is gaseous and at 100$^{0}C$ is both gaseous and liquid.
