Question

a 1 - l soda bottle contains dissolved carbon dioxide gas. which bottle would have the highest concentration of dissolved gas?
a bottle that is sealed
a bottle that was opened 1 minute ago
a bottle that was opened 1 hour ago
a bottle that was opened 1 day ago

Explanation:

Step1: Understand gas - solubility principle

When a soda bottle is sealed, the carbon - dioxide gas in the bottle is in a state of equilibrium with the dissolved carbon - dioxide.

Step2: Analyze opened bottles

Once the bottle is opened, the pressure above the liquid decreases, and the equilibrium shifts to release carbon - dioxide gas from the solution. The longer the bottle is open, the more gas escapes.

Answer:

a bottle that is sealed
