Question

Why does carbon dioxide escape when you open the can of soda?

Answer 1

Because it was bottled under high pressure and the atmospheric pressure is less. Carbon dioxide only dissolves at higher than normal pressure.

EXPLANATION:

Soda water, like other carbonated beverages, contains carbon dioxide that has dissolved under pressure. When the pressure is released by opening the soda container, the liquid cannot hold as much carbon dioxide, so the excess bubbles out of the solution.

Answer 2

Answer:

Explanation: An unopened soda can is virtually bubble-free because the pressure inside the can keeps the carbon dioxide dissolved in the liquid.
