Henry's law when pressure changes fast

[mosafer1980]

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,

Thank you,

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