Understanding Archimedes Principle: Observing Bubble Size in Rising Water Column

Click For Summary

Homework Help Overview

The discussion revolves around understanding the behavior of bubbles rising in a column of water, particularly focusing on the observation that their diameter increases as they ascend. Participants are exploring concepts related to fluid dynamics and pressure, with references to Archimedes' Principle and Pascal's Law.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the relevance of Archimedes' Principle to the observed phenomenon and are considering the relationship between pressure and volume in the context of ideal gases. There is also inquiry into the role of static pressure in fluids.

Discussion Status

The discussion is ongoing, with participants providing different perspectives on the principles at play. Some guidance has been offered regarding the relationship between pressure and volume, but there is no explicit consensus on the underlying principles involved.

Contextual Notes

Participants are navigating assumptions about the behavior of gases in fluids and the implications of static pressure, indicating a need for further clarification on these concepts.

Homework Statement

It`s not to calculate, actually, I am just trying to understand this. I think it has to do with Archimedes Principle, but could anyone explain the following more clearer to me?

"It`s observed that as bubbles rise in a deep column of water, the diameter of the bubbles increases."

Homework Equations


The Attempt at a Solution

I don't think it's particularly related to Archimedes' principle. Instead, think of the bubble as being an ideal gas. How are pressure and volume related? How does pressure in the fluid change as the bubble rises?
 


does it have to do with Pascal`s then?

Not especially. It has to do with static pressure in a fluid. What does it depend on?
