AI Thread Summary
Henry's law is applicable at the interface between gas and liquid, but its application becomes complex during rapid pressure changes. When pressure increases quickly, there may not be sufficient time for gas to dissolve into the liquid, potentially leading to the conclusion that no air dissolves. The discussion highlights the need for mathematical modeling to better understand the dynamics involved in such scenarios. Resources or equations that address these rapid changes are sought for further clarity. Understanding these principles is crucial for accurately applying Henry's law under varying pressure conditions.

Hello everybody,

I know that we can just apply Henry's law when there is a thermodynamic balance between for example air bubbles and liquid. Consider that we are having a liquid with some gas bubbles entrained in it. How can we apply Henry's law when we increase pressure rapidly. can we just say that in this case no air dissolves, because there is a rapid change in pressure and no time for the gas to go in solution. Any mathematical equations for it or any resource will be greatly appreciated.

Thank you,

In such cases, Henry's law applies only at the interface between the liquid and gas
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
