Question

1. if each of these bottles of carbonated water initially contained the same amount of dissolved carbon dioxide, which bottle will contain the least amount of dissolved carbon dioxide after 15 minutes?

options: bottle 3, bottle 4, bottle 1, bottle 2

Explanation:

1. Temperature effect: Gases like CO₂ are less soluble in warmer liquids, so warm water will hold less dissolved CO₂ than cold water.
2. Pressure effect: A sealed cap keeps CO₂ gas trapped above the liquid, maintaining higher pressure which helps keep CO₂ dissolved. An open cap allows CO₂ gas to escape, lowering pressure and reducing dissolved CO₂.
3. Combining both: The warm, uncapped bottle (Bottle 4) has the highest temperature and no pressure retention, so it will lose the most dissolved CO₂, leaving the least amount remaining.

Answer:

Bottle 4
