Fizzing and Popping

[freak93]

This is kind of a random question but today i was shooting the cap off a spring water bottle (if you don't know how to do and want to know just reply and i'll tell you) and i spun it as tight as i about could and when the cap shot off the water inside started fizzing and popping along with smoke coming out which normally happens.

Would this start fizzing after it shot because there was too much pressure for it to happen and once it all released to started. The reason i asked this question is because i thought that matter got colder when it expanded and if this was getting cooler that would make it fizz would it.


any replies would be great.

matter contracts when cooled, expands when heated up.

But water is the exception to that rule. It expands when it freezes. and shrinks when it melts. The "smoke" you saw was probably a condensation cloud or mist from the bubbles. Carbonated water of course will fizz when exposed to atmospheric pressure or agitation from shaking or vibration. Some objects can cause a rapid release of the carbonation, mostly due to the large surface areas for bubble formation.

ah yes, thanks for correcting me hatter. Had forgotten about that little rule. Doh!

the water wouldn't have enough carbon for that would it?
