saturation temperature

**saturation temperature**

The saturation temperature is the temperature at which a substance changes phase between liquid and vapor at a given pressure. In other words, it is the temperature at which a liquid boils or a vapor condenses when in equilibrium with its vapor or liquid phase. This concept is fundamental in thermodynamics and is commonly used in fields such as HVAC, refrigeration, and chemical engineering to describe phase transitions and heat transfer processes. The saturation temperature varies with pressure-higher pressures correspond to higher saturation temperatures and vice versa. Understanding saturation temperature is essential for designing efficient thermal systems and managing phase change phenomena.
