Distillation is a chemical process that utilizes the difference in （ ） between two substances to achieve separation. 12. Under certain conditions, the pressure at which the vapor and liquid phases reach equilibrium is called the （ ） under those conditions. 13. The saturated vapor pressure of a substance is mainly related to the substance’s ( ) ( ). 14. At the same temperature, the greater the saturated vapor pressure of different liquids, the greater their volatility, and the higher their boiling point. 15. The methods for desorbing gas from a solution are ( ) ( ) ( ) ( ). Answer: 11. Answer: Volatility (boiling point). 12. Answer: The saturated vapor pressure of that liquid. 13. Inherent properties and temperature. 14. Answer: High, Low. 15. Answer: Heating, flashing (decompression), stripping, distillation (rectification). It should be noted that respondents are required to keep their answers hidden. If the answerer’s score is not hidden, it is halved.

11. Distillation is a chemical process that utilizes the difference in (volatility (boiling point)) between two substances to achieve separation. 12. Under certain conditions, the pressure at which the vapor and liquid phases reach equilibrium is referred to as the (saturation vapor pressure of that liquid) under those conditions. 13. The saturated vapor pressure of a substance is primarily related to the substance’s (temperature, ) (properties such as volatility and boiling point). 14. At the same temperature, the higher the saturated vapor pressure of different liquids, the greater their volatility, and the lower their boiling point. 15. The methods for desorbing gas from a solution include (heating), (flash evaporation (depression)), (stripping), and (distillation (rectification)).
