# Can gas return back into a sparkling beverage on cooldown?

We all know that if a sparkling beverage (let's say, CocaCola) spends some time outside of the fridge and gets warm, the gas comes out of the liquid, rises the inner pressure and makes the bottle walls more tight and the cap to curve outwards. Also, drinking this does not seem very tasty. My question is this: if I cool down the bottle again, will the gas be re-absorbed by the liquid and will the drink restore its qualities?

Edit: sorry, could not add tags like gas or liquid since they do not exist yet :D, and I do not have enough reputation.

• What has been your own observation of this? – Floris May 27 '15 at 15:00
• @Floris: I have experimented with this a couple of times and I get a little confused: the drink does not really taste the same, although it seemingly gets some gas back. I judge this by the fact that when I open the cool again bottle, there is no big gas blast and there are sparkles in the liquid. However, can it be that the gas just lowered its pressure without coming back into the liquid so that it stopped pushing the walls, and the sparkles in the liquid is just some part of the gas that did not exit it because it came to some equilibrium of some part of gas being inside the liquid and not? – noncom May 27 '15 at 15:09
• @noncom Would Chemistry SE be a better home for your question? – Gonenc May 27 '15 at 16:08
• @gonenc: quite possible! i just cannot really tell if this one belongs more to physics or chemistry, but well may be you're right! Can we move it somehow.. ? – noncom May 27 '15 at 16:12
• @gonenc. This is at most chemical physics, but basically this is thermodynamics, i.e. physics and not chemistry. Hence, the tags are almost ok. – mikuszefski May 27 '15 at 17:05
