Answer :
To solve the given problem, let's break it down into the two scenarios described in the question and determine the predicted outcomes based on the available information.
### Scenario 1: Forces on Wire Loops
In this scenario, we are dipping identical wire loops into two different liquids, Liquid A and Liquid B, forming a film of liquid across these loops. We are then measuring the forces [tex]\( F_A \)[/tex] and [tex]\( F_B \)[/tex] required to make the loops 5% wider.
Key considerations:
- The force required to increase the width of the loops depends on the surface tension of the liquids.
- Surface tension is a property that varies between different liquids.
- Without knowing the specific surface tensions of Liquid A and Liquid B, we cannot directly compare [tex]\( F_A \)[/tex] and [tex]\( F_B \)[/tex].
Conclusion:
Since we don't have information about the surface tension values of Liquid A and Liquid B, it is impossible to predict whether [tex]\( F_A \)[/tex] will be greater than, less than, or equal to [tex]\( F_B \)[/tex].
### Scenario 2: Boiling Points in Sealed Flasks
In this scenario, we have 15.0 mL of Liquid A in one sealed 5 L flask, and 15.0 mL of Liquid B in another sealed 5 L flask. The pressure in each flask is lowered slowly with a vacuum pump, and we want to predict which liquid, if any, will boil first.
Key considerations:
- Boiling occurs when the vapor pressure of the liquid equals the external pressure.
- Different liquids have different boiling points and vapor pressures.
- Without information on the boiling points or vapor pressures of Liquid A and Liquid B, it is impossible to determine which liquid will boil first or if either liquid will boil under the given conditions.
Conclusion:
Given that we do not have the specific boiling points or vapor pressures for Liquid A and Liquid B, it is impossible to predict whether Liquid A or Liquid B will boil first, or if either will boil at all.
### Final Summary
Experiment 1:
- Predicted Outcome: It's impossible to predict whether [tex]\( F_A \)[/tex] or [tex]\( F_B \)[/tex] will be greater without more information.
Experiment 2:
- Predicted Outcome: It's impossible to predict whether either Liquid A or Liquid B will boil without more information.
This step-by-step analysis concludes that in both scenarios, without additional specific information about the properties of the liquids involved, no definitive prediction can be made.
