Question

Which reason explains why gas bubbles are released when a carbonated beverage is opened?

A. Decreasing the pressure increases the rate of solution.
B. The solubility of a gas in a liquid decreases with decreased pressure.
C. Exposing a liquid to air causes it to become a saturated solution.
D. The solvent changes from a liquid to a gas when the beverage is opened.

Answer 1

B. The solubility of a gas in a liquid decreases with decreased pressure.

Step-by-step explanation:

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. If the soda is left open, additional carbon dioxide will slowly escape into the air. Under warm conditions, the carbon dioxide leaves the solution faster
