What is saturation temperature?

Saturation temperature is the temperature at which a substance changes from a liquid state to a gas state, or vice versa, at a particular pressure. This temperature is specific to each substance and pressure level, and is often used in thermodynamics and phase change calculations.

For example, the saturation temperature of water is 100°C at standard atmospheric pressure (1 atm). This means that water will boil and turn into steam at this temperature under normal atmospheric conditions.

Saturation temperature is an important parameter in refrigeration, air conditioning, and industrial processes where phase changes are involved. It can be used to determine the state of a substance (liquid, vapor, or mixture) and to calculate the amount of heat transfer required for a phase change to occur.

Overall, saturation temperature is a key factor in understanding and controlling phase changes in various processes and systems.
