Question

Why soda water bottle kept at room temperature fizzes on opening?

Short/Brief Note
Advertisements

Solution

To increase the solubility of CO2 in soft drinks, the soda water bottles are sealed under high pressure. When the bottle is opened at room temperature under normal atmosphere conditions, the pressure inside the bottle decreases to atmospheric pressure and excess CO2 fizzes out.
