    Air Fall Rain Vapor

Discussion Overview

The discussion centers around the behavior of air humidity and its potential to condense in a room following a drop in temperature. Participants explore the conditions under which water vapor might condense and the mechanisms involved in this process, including comparisons to natural phenomena like rain formation.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions whether high humidity due to elevated temperatures can lead to condensation that falls like rain when the temperature drops.
  • Another participant acknowledges that while it won't fall like rain, it may drip, indicating a belief in some form of condensation occurring.
  • A third participant notes that condensation typically manifests as mist or fog rather than droplets, suggesting a different form of humidity expression.
  • Another viewpoint suggests that raindrops form through a process involving cold air and vapor, with condensation occurring on cold surfaces, such as an air conditioning vent, but questions whether condensation can form in the air itself.

Areas of Agreement / Disagreement

Participants express differing views on the nature of condensation in a room, with no consensus on whether it can fall like rain or how it manifests under varying conditions.

Contextual Notes

Participants mention assumptions about temperature drops and humidity levels, but do not fully explore the implications or limitations of these assumptions. The discussion does not resolve the mechanics of condensation in indoor environments.

Hello,


I wanted to know if air humidtiy is high because of a higher temperature does it fall like rain on me or on the clothes or ground what ever after a drop in temperature?

The drop in Temperature also means a drop in humidity where does the water vapor goes, i know about cold places in a room where it condense but can it also condense just in a minute when i open the window and the colder air drops the temperature of the room?

How is the process can anyone explain it to me why we are still dry?

thanks!

I know for a fact it won't fall like rain however it will drip.
Please notify me if you need more information.
 
Condensation due to drop in temperature and high humidity is usually in the form of mist or fog, not drops.
 
My assumption is that raindrops form and grow due to falling long distances through clouds. If they begin at a high cold altitude, the drop would be cooler than the vapor it passes through, causing it to condense that vapor as it comes in contact with it.

Humidity in a room would condense on anything cold it touches, such as a cold beverage or an air conditioning vent. Theoretically, I suppose, cold air from an a/c could also generate drops of condensation in the air itself, but I would think these drops would immediately evaporate into the surrounding cold air from the a/c. The only reason I think condensation might form on the a/c vent itself is because it is metal and holds temperature and because the warm humid air would creep in from the walls as the air stream blows away from the ceiling.
