Homework Statement
Does flowing water absorb and release air?
Click For Summary
Homework Help Overview
The discussion revolves around the question of whether flowing water can absorb and release air, particularly focusing on the dynamics of gas exchange in water. The subject area includes concepts related to fluid dynamics and gas solubility.
Discussion Character
- Exploratory, Conceptual clarification, Assumption checking
Approaches and Questions Raised
- Participants explore the relationship between the flow of water and its ability to absorb or release gases, questioning how stirring or splashing affects gas content. There are inquiries into the implications of volume changes when substances interact.
Discussion Status
The discussion includes various perspectives on gas exchange in water, with some participants suggesting that vigorous flow increases dissolved oxygen, while others propose that oxygen can be released into the air. There is no explicit consensus, but multiple interpretations are being explored.
Contextual Notes
Participants are considering assumptions about gas solubility and the conditions under which gases are absorbed or released, including the effects of flow dynamics and gradients.

if some subtance A absorbs another substance B, what would happen to the volume of substance A.
take a glass of water and stir it. WHat happens to the volume of water in the glass?
(Assuming you didnt spill any water out of the glass

Yes it does, and the more vigorous the flow, the higher the dissolved oxygen content, generally.

so basically if you splash water or something like that the water can release some of its oxygen content into the air.

Usually its more the other direction, oxygen gets entrapped--look at the gradients to understand why, while H2S and some other undesireable gasses are released.
