# Question #389db

Normal atmospheric pressure and room temperature correspond to a pressure of 1 atm and a temperature of $\text{20-25"^@"C}$. Let's use the 1-atm pressure as a reference value, since it's highlighted on the diagram with a dash line.
Notice that, at 1 atm, water can exist as a solid only at temperatures below ${0}^{\circ} \text{C}$. Likewise, it can only exist as a gas at temperatures that exceed ${100}^{\circ} \text{C}$.
At this pressure and at any temperature higher then ${0}^{\circ} \text{C}$ and lower than ${100}^{\circ} \text{C}$, water can only be a liquid.
