# At pressures greater than 1 atm, what will water boil at?

By definition, the $\text{boiling point}$ of a liquid is the conditions of temperature and pressure when the $\text{vapour pressure}$ of the liquid is equal to the ambient pressure and bubbles of vapour form directly in the liquid. The $\text{normal boiling point}$ is specified when the ambient pressure is $1 \cdot a t m$.
If the ambient pressure is somehow increased the temperature required for $\text{boiling}$ also increases.
