Temperature's Impact on Sound Transfer: Is There a Connection?

Click For Summary

Discussion Overview

The discussion centers on the relationship between temperature and surface tension (ST) in liquids, specifically exploring how these factors influence the sound produced by splashing water. Participants question whether there is a mathematical relationship between temperature and ST, and how this might affect the auditory characteristics of splashes from hot versus cold water.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant inquires about the mathematical relationship between temperature and surface tension, suggesting that sound produced by splashes may vary with temperature.
  • Another participant asserts that surface tension decreases with increasing temperature due to increased molecular motion disrupting intermolecular bonds, implying a connection to sound production.
  • Some participants propose that hot water (HW) splashes differently than cold water (CW) due to lower surface tension, allowing drops to fall independently and create distinct sounds.
  • One participant expresses uncertainty, noting conflicting information that HW may splash less and produce quieter sounds than CW, questioning the validity of their initial theory.
  • There is mention of steam bubbles in hot water potentially affecting sound, raising questions about the role of surface tension in this context.
  • Participants are encouraged to conduct experiments to observe the differences in sound between hot and cold water splashes.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the relationship between temperature, surface tension, and the resulting sound of splashes. Multiple competing views are presented, with some asserting a connection while others question or contradict these claims.

Contextual Notes

There are unresolved questions regarding the mathematical relationship between surface tension and temperature, as well as the influence of fluid dynamics on sound production. Participants express varying interpretations of how these factors interact.

How does ST vary with temerature? Is there a mathematical relationship?
Also, does the sound water make on splashing have anything to do with its ST?Like,hot water makes a different sound from cold water etc.
 
Physics news on Phys.org
Surface Tension lowers with increasing temperature as the increasing motion of the molecules disturbs the bonds between the molecules in the liquid.

There almost certainly is a relationship for it...

Why don't you try the last question you asked? I assume you have a kettle at home, you can let us know what happened.
 
I think HW splashes more and sounds different from CW(I can't really express the difference in words though) because due to its lower ST the drops fall independent of each other and each produces its own splash and sound. But I think there is another reason for it too, though I cannot say exactly what. Could someone please shed some light on this? And also on the mathematical relation b/w ST and temp. ?

:rolleyes: But I read somewhere later that HW actually splashes less and makes less sound than CW.Then what is wrong with my above theory?And is the second reason related to fluid dynamics?Just wondering.

Still WAITING...
 
The link does not have an answer ,only the same question.
 
I read somewhere that HW sounds different from CW because of steam bubbles in it Where does thet leave ST?Does it have no role to play?
