Hint: Water is found to exist in the triple point it means water can exist in all the three states of liquid, solid and gas. The latent heat of fusion of water at the freezing is about 334 Joules. Latent heat is the required energy for the conversion from liquid to a gaseous state. The boiling point of water is $\text{100}{}^\circ \text{C}$ and the melting point of water is $0{}^\circ \text{C}$.

> When the temperature of the water reaches up to $0{}^\circ \text{C}$, then the water starts to convert from the solid state to the liquid state.
> Similarly, when the temperature of the water reaches up to $\text{100}{}^\circ \text{C}$, then the water starts to convert from the liquid to the gaseous state.
> Now, when the temperature of the water reaches up to $\text{250}{}^\circ \text{C}$. We can see that the temperature of the water is above $\text{100}{}^\circ \text{C}$ so it is confirmed that the water is completely converted into the gaseous state.
> Therefore, we can say that the physical state of the water at $\text{100}{}^\circ \text{C}$ is both liquids as well as gaseous state and at $\text{250}{}^\circ \text{C}$ the physical state of the water is gas.
Note: Water is a polar substance with maximum density at $\text{4}{}^\circ \text{C}$. Water is also considered as the universal solvent because it tends to dissolve most of the liquids and acts as a solvent.
