Question

When a bottle of soda water is opened, carbon dioxide escapes, producing a fizz. This is due to:

• A. Decrease in solubility on increasing temperature
• B. Decrease in solubility on decreasing temperature
• C. Decrease in solubility on decreasing pressure
• D. Decrease in solubility on increasing pressure

Hint:

Remember, gases are more soluble in liquids at lower temperatures and higher pressures.

Answer 1

The Correct Option is A

When soda water is opened, the carbon dioxide gas, which was dissolved under high pressure inside the bottle, escapes as the pressure is released. This is because the solubility of gases in liquids decreases with increasing temperature.
Therefore, the correct answer is "Decrease in solubility on increasing temperature."
