Surface Tension of Water: The Effects of Syrup on Surface Tension

Click For Summary

Discussion Overview

The discussion revolves around the effects of syrup on the surface tension of water, exploring whether syrup increases or reduces this property. Participants consider various factors such as the type of syrup, concentration, and temperature, while also referencing a video that prompted the inquiry.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant questions whether syrup increases or reduces the surface tension of water, seeking clarification on the context of the question.
  • Another participant notes that water is sensitive to contamination, suggesting that small impurities can significantly affect interfacial energy, and emphasizes the need for specifics regarding the type of syrup and its concentration.
  • A participant references a video that inspired their inquiry, speculating on the theoretical implications of surface tension and the potential effects of adding syrup.
  • One participant asserts that the interfacial energy of a solution is always less than that of pure solvent, implying that syrup would reduce surface tension.
  • Another participant acknowledges the trick nature of the video but expresses interest in the physical implications of the discussion.

Areas of Agreement / Disagreement

Participants express differing views on whether syrup affects surface tension positively or negatively, with no consensus reached on the matter.

Contextual Notes

Participants highlight the importance of specific conditions such as syrup type, concentration, and temperature, which remain unresolved in the discussion.

Hello. I'd like to ask: does syrup increase or reduce the surface tension of water? Thanks.

What is the context of your question? Why do you ask?
 
Water is very sensitive to contamination- small impurities can have large effects on the interfacial energy- specifically, the interfacial energy will drastically drop.

If you are looking for a quantitative number, you have to be more specific- what kind of syrup? what is the ratio syrup/water? what temperature?
 
Well, I think I should've explained it in the question :)

I'm just thinking about the surface tension because of this video: http://www.youtube.com/watch?v=7ctaA2mERzI"
I think it could theoretically be possible if the surface tension was strong enough and not disturbed by things such as bubbles etc. And I was thinking if it would be more realistic if syrup (or something else) was added to the water. I just don't know if the syrup would increase or reduce the surface tension.

EDIT: Andy Resnick: So does the first line of your post mean that there isn't any substance that could increase the surface tension (because it would always mean polluting the water)?

You do realize the video is a trick/joke, right?

AFAIK, the interfacial energy of a solution is always less than the pure solvent.
 
Yes, I realize that. But that doesn't have to prevent me from thinking of the psychical side of it.
Anyway, thanks for your answers.
