Does soda ( carbonated beverages ) go flat faster in the refridgerator?

Question

It just seems so. I'm wondering if anyone knows why.

If it is in a plastic bottle that is capped, I swear it seems to go flat faster in the fridge. Can someone please verify this? I'm adding this after the first answer was answered, by the way.

Answer 1

The solubility of a gas in a liquid depends on temperature and pressure. An unopened bottle of soda will keep its carbonation for quite a while in or out of the refrigerator. So, temperature is the key here. If you keep a liquid cold, it will retain dissolved gases longer.

However, if you take open bottles of soda, put one in the fridge and put one on the table at room temperature, the warmer one will lost carbonation (go flat) faster.

Answer 2

I think they go flat faster at room temperature. The carbonic acid reacts more vigorously at higher temperatures, making more fizz pressure, so the total fizz goes faster.A cooled soda will have fizz longer, but with less pressure. If you put a soda in the freezer, it will reach a point where it won't fizz out when you open it, somewhere between all liquid and mostly solid. Too warm or too cold, and it gets wild.

Answer 3

Actually, soda should go flat faster when oustside the refrigerator, in higher temperatures. This is so, as when the temperature is higher the gaseous molecules have more kinetic energy, hence they are able to escape the solution faster. Contrast this to having a lower temperature where the molecules have lower kinetic energies resulting to them being dissolved in the solution longer. In short, the higher the temperature the less gas tends to be dissolves in a liquid solution, the faster it becomes flat.

Answer 4

If they are not open and the seal is not broken, carbonation stay the same, refrigerated or not because the pressure is constant.

Answer 5

The cooler the less active the CO2.
