how does a shaken can of soda lose its pressure over time, if its sealed?
In: Chemistry
The CO2 is dissolved in the liquid because it’s under pressure. They CO2 leaves the liquid in the form of bubbles usually slowly. When you shake a soda, you’re creating tons of tiny bubbles that the co2 can escape from (like the foam heads after pouring) causing a huge burst of gas if opened right away. However, if you leave that shaken soda alone for a while, the CO2 released isnt escaping from the can, but dissolving back into the liquid.
Then pressure is still the same. The difference is whether or not the CO2 is dissolved in the liquid or not.
