Discussion Overview

The discussion revolves around whether stirring a fluid can lead to the separation of particles within that fluid. Participants explore the implications of stirring in terms of particle distribution and the conditions under which separation might occur, focusing on both theoretical and conceptual aspects.

Discussion Character

  • Homework-related, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant suggests that stirring a fluid, such as tea with sugar, integrates the components rather than separating them.
  • Another participant requests clarification on what is meant by "separate the particles," indicating the need for specificity in the question.
  • A follow-up response reiterates the need for specificity, asking whether stirring would help in spreading out the particles.
  • Another participant emphasizes the importance of defining the type of particles being discussed to address the question accurately.
  • A hypothetical scenario is presented where air particles in a box are stirred, questioning whether this action would lead to a more even distribution or cause the particles to clump together.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, as there are multiple interpretations of what "separating particles" entails, and the discussion remains unresolved regarding the effects of stirring on particle distribution.

Contextual Notes

The discussion highlights the ambiguity in the term "separate the particles" and the need for clear definitions of the particles involved, as well as the conditions under which stirring is applied.

Homework Statement


Would stirring a fluid separate the particles?

Homework Equations

The Attempt at a Solution


You stir tea to integrate the tea and the sugar so I would say that stirring would not separate the particles.

Any help?

Thanks!

You need to be more specific. What do you mean by "separate the particles"?

I mean that if you wanted to spread out the particles would you stir the fluid or not.
 
You will need to define what particles you are referring to.
 
So if you put some air particles in a box and they spread out fairly evenly over the volume of the box, you then start to stir the particles in the box. Will the particles become more spread out or will they actually start to clump up and get closer together?
