Why do bubbles come out when a cold drink bottle is opened?
Answer and explanation
Correct answer: Pressure suddenly decreases
A carbonated drink contains dissolved carbon dioxide under pressure. While the bottle is closed, the high pressure helps keep more carbon dioxide dissolved. Opening the bottle suddenly lowers the pressure above the liquid, so the gas becomes less soluble and escapes as bubbles. The bubbles are therefore mainly due to pressure reduction, not freezing or a large temperature rise.
