Why soda “calms down” when you close the cap after opening it once? Why it doesnt explode the next time you open the bottle?

Question

I mean no gases were leaked from the bottle while the cap is closed so why is it doing that.

Answer 1

The gases leaked out when you opened it the first time, and that gave the pressure time to equalize between inside and outside the bottle, so there’s no need for that to happen again unless something causes another change in the pressure. You can increase the pressure in the bottle again after closing it and make it hiss again when you open it, but unless this is done intentionally, it won’t usually happen.
