Discussion Overview

The discussion revolves around the accumulation of dust in a closed apartment that has not been occupied for three months. Participants explore the relationship between entropy and dust accumulation, questioning the factors that contribute to dust presence in seemingly clean environments. The conversation touches on concepts from thermodynamics, airflow, and environmental conditions.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions the relevance of entropy to the accumulation of dust in a closed apartment, suggesting that the thermodynamic concept may not apply to this situation.
  • Another participant points out that dust is composed of various organic materials, implying that even a clean apartment can accumulate dust from other sources.
  • Some participants argue that a 'closed' apartment is not truly closed due to potential airflow from heating or air conditioning systems, which could introduce dust.
  • There is a suggestion that maintaining a messy environment might prevent dust accumulation, contrasting with the idea that cleanliness leads to dust buildup.
  • A participant raises a hypothetical scenario about a nearly-airtight home in Europe, questioning whether it would still accumulate dust, indicating uncertainty about the effects of airtightness on dust levels.
  • One participant humorously mentions "dried ectoplasm," contributing to the light-hearted tone of the discussion while acknowledging the complexity of the topic.
  • The original poster shares their experience of returning to a clean apartment only to find it dusty, despite taking measures to keep it spotless, which raises questions about the sources of dust in such environments.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between entropy and dust accumulation, with no consensus reached on the applicability of thermodynamic principles to the situation. There is also disagreement regarding the factors contributing to dust presence in closed spaces.

Contextual Notes

Participants mention various assumptions about airflow, cleanliness, and environmental conditions that may influence dust accumulation, but these assumptions remain unresolved within the discussion.

Entropy and Dust!

I don't know if this goes here or in the Chemestry forum, I Want to Know Why a Closed House gets Filled with Dust...i have an Apartment in another state for vacation, we had´nt been there since 3 month ago...this past weekend we went and the Apartament which we left completely clean and with all windows closed...was super dusty...i recall reading about Entropy having something to do with that but I am not sure...what do you think!...
 
Science news on Phys.org


Dust is made out of dustmite excrement, other insect parts, and human flesh. You subtracted the human flesh, but the rest still builds up. You are not the only resident of your house.
 


I have heard a lot of explanations and analogies for entropy involving cleaning and order and whatnot. Maybe this is why you think that entropy has something to do with this. The thermodynamic concept of entropy probably has as little to do with your situation as it does with anything else.
 


Also, a 'closed' apartment is not closed. Do you have AC/heating? That brings in dirty air. Even if it was turned off; there's still airflow throughout the apartment.

You're saying a house works like a silt trap to the surrounding atmosphere?
So you think a vacant European nearly-airtight (with air-exchanger closed) home wouldn't significantly accumulate dust?
 


In fact dust doesn't usually gather in places with high entropy :smile:

(you need to mess the place up once a week, then it will be messy but no dust will gather in the messy places)

All I know is that my house is drafty in winter.
 


Dried Ectoplasm.
 


jajaja Dried Ectoplasm! no seriously...thank you all...im starting to get an insight...anyway...my wife is a cleansing freak...she left the apparment totally spotless...you could pass a finger with a white glove and find nothing...the apartment doesn't have any Hvac system...if you want air, open the windows...so...we left the apt. super clean, we don't have rugs...all windows super closed, none food rest, clean sheets on beds...etc...3 month later...low dusty (not visible touhg)...enough that i had allergie...
