I'm not sure how to answer this question. The correct answer is in red.
Liquid A is known to have a higher vapor pressure and higher surface tension than Liquid B. Use these facts to predict the result of each experiment in the table below, if you can. experiment 25.0 mL of Liquid A are poured into a beaker. 25.0 mL of Liquid B are poured into another beaker. After 90 minutes have passed, the volumes V and VB of liquid in A each beaker are measured. 25.0 mL of Liquid A are put in one sealed 5 L flask, and 25.0 mL of Liquid B are put in another sealed 5 L flask. The pressure in each flask is then slowly lowered with a vacuum pump. A A A predicted outcome will be greater than V will be less than VB will be equal to B It's impossible to predict whether VA or VB will be greater without more information. O Eventually both liquids boil, A first and then B. Eventually both liquids boil, B first and then A. O Neither liquid will boil It's impossible to predict whether eitherliquid boils without more information. X
