Henry's Law

[blazinfury]

I am trying to understand the applicability of Henry's Law, but am having some difficulty.

 

 

The law makes sense but I find limited utility in it because the increase in solubility occurs at a constant temp and in a closed container. So in that case, is the only way to increase the VP of a gas by physically disturbing it-- ie like shaking a soda can? I am just trying to understand when it would apply since it seems that it really cannot work in our atmosphere due to it being an open system and with frequent temp fluctuations. Thanks.
