saturation pressure

Saturation pressure refers to the pressure at which a gas, like water vapor, is in balance with its liquid form at a specific temperature. When the temperature increases, the saturation pressure also rises, allowing more vapor to exist before it condenses back into liquid. If the pressure drops below this level, condensation occurs, creating droplets, like when dew forms. Understanding saturation pressure helps explain weather phenomena, such as cloud formation and rain, and is important for processes in fields like meteorology, engineering, and environmental science.
