Under those extreme conditions, the gas fully dissolves in the liquid. The temperature of water at carbonation is also critical. Water that's carbonated at near-freezing temperature 32 degrees Fahrenheit or 0 degrees Celsius can hold five times as much C02as water that's carbonated at degrees F 60 degrees C [source: America's Test Kitchen ].
Inside the pressure chamber, carbonated water has absolutely no fizz. The bubbles only emerge when the liquid is released from the chamber back into normal atmospheric pressure. Carbonated water contains 16, times more C02than regular water, roughly five "glasses" of C02 for every glass of water [source: Discovery ]. When you pop the cap on a soda bottle, the release of pressure causes all of those dissolved C02 molecules to become gas again and rush to escape through the surface of the liquid as bubbles.

For that reason, I don't generally use my machine for anything but water anymore. If you're using a CO 2 tank and carbonator cap or similar rig, keep in mind that the tank can put out gas at hundreds of PSI, so a regulator is critical. Most plastic and glass bottles can handle somewhere between and PSI, but this can change depending on the atmospheric temperature and whether the bottling material has any flaws or defects.
If you're chasing high pressures, make sure that the bottle you're using can handle the pressure—in any situation. Here's an example of what I mean: let's say you carbonated a soda in a glass bottle designed for still wine. At room temperature, the bottle would probably only be experiencing around PSI—no problem for the bottle, and just fine, from your regulator's perspective.
If, however, you took that bottle and shook it, gas would rapidly come out of solution, raising pressures to 90 PSI. And if the bottle happened to be in direct sunlight when it was hot out at the same time, the pressure would increase even more. And what if then, you dropped it from a height of a few feet, right where the glass happened to be weak? Here's what I'm trying to say: Always use a bottle that is rated for well above the maximum PSI you think you'll be exposing it to.

Chemists call this an equilibrium: The pressure of the CO2 gas stops the CO2 dissolved in the water from escaping, and the amount of CO2 dissolved in the water stops the gas from dissolving into the water. Although the amount of CO2 that can be dissolved in water decreases as the temperature rises, this equilibrium will still hold.
Chemists call this a supersaturated solution: The water is holding onto more CO2 than it would absorb at that temperature. It has nowhere to go until you open the bottle, or the pressure of the gas breaks or bursts the bottle. Plastic bottles and metal cans are incredibly strong, but they do burst.
You'll see this phenomenon if you leave a can of Coke in a hot car for a long time. One odd quirk of carbonation is what happens if you freeze a carbonated drink: The bottle or can usually bursts.
Given that cold water holds more CO2 than warm, you might expect the opposite to happen. But cold water and ice are not the same thing, and CO2 is not soluble in ice.
When you freeze a bottle of soda, the water freezes and forces out the CO2. This creates a huge amount of gas pressure inside the can. Eventually, the combination of this pressure and the expansion of the ice which is less dense than water will burst the bottle or can. That's why you don't freeze sodas. It also explains the effectiveness of giving someone a can of soda that has been in the freezer for a bit so it gushes out when they open it. The near-freezing soda is pushing the CO2 out, which creates the pressure for the prank to work.
When you open a can or bottle of soda, you break the equilibrium. The gas rushes out and reduces the pressure on the water surface. Suddenly, the CO2 dissolved in the water has somewhere to go, so it starts to escape. It doesn't just rush out of the top, though. Small bubbles form that grow larger as they rise.
That's because these bubbles are small surfaces in the water, and more of the CO2 rushes in as they rise. These bubbles don't just form anywhere, though. They usually start on the surface of the glass, bottle or can that the drink is in because tiny imperfections in the surface form a spot for the minute starter bubbles to form.
