saturated vapor pressure
Thread Content
May I ask why, when the operating pressure is greater than the saturated vapor pressure at the current temperature, the liquid phase still vaporizes? How is the gasification volume calculated?
Vaporization and liquefaction are interconnected processes.
Thank you for your reply. I thought about it further, and this issue can be explained in terms of the thermal motion of molecules. When there is high external pressure or low temperature, the distance between liquid molecules decreases, resulting in increased forces that reduce the likelihood of molecules escaping; however, this does not completely prevent molecules from escaping.
This can only happen as a dynamic process; of course, the level of molecular movement you’re referring to goes beyond the scope of chemical engineering
