At atmospheric pressure, the saturation temperature is 100°C. However, if the pressure is increased, this will allow the addition of more heat and an increase in temperature without a change of phase. Therefore, increasing the pressure effectively increases both the enthalpy of water and the saturation temperature.

Effect of Pressure on Steam Formation Temperature
Pressure has a significant impact on the temperature at which water boils and turns into steam. When pressure increases, the temperature required for steam formation also increases. This relationship is governed by the principle of phase equilibrium.
Explanation
- When water is heated, it absorbs energy and its temperature rises. At the boiling point, the temperature remains constant as the energy supplied is used to break the intermolecular forces holding the water molecules together.
- Increasing the pressure on the system raises the boiling point of water. This is because higher pressure makes it harder for water molecules to escape into the gas phase, requiring more energy and thus a higher temperature.
- Conversely, decreasing the pressure lowers the boiling point of water, as the molecules can escape more easily into the gas phase.
- At extremely high pressures, the boiling point of water can increase significantly. For example, in a pressure cooker, the higher pressure allows water to reach temperatures above its normal boiling point, resulting in faster cooking times.
Conclusion
In conclusion, when the pressure is increased, the temperature required for steam formation also increases. This relationship between pressure and temperature is crucial in various industrial processes and everyday applications where steam is utilized.
