Question

If a soft-drink bottle whose volume is:

A) Full, it will overflow
B) Empty, it will collapse
C) Pressurized, it will expand
D) Squared, it will rupture

Answer 1

When a carbonated beverage bottle is opened, the CO₂ pressure above the liquid decreases, causing bubbles of CO₂ to rapidly exit the solution and escape from the top of the bottle. If the bottle is left open, more and more CO₂ comes out of the liquid, making the beverage 'flat'.

Step-by-step explanation:

When carbonated beverages are packaged, they are done so under high CO₂ pressure so that a large amount of carbon dioxide dissolves in the liquid. When the bottle is open, the equilibrium is disrupted because the CO₂ pressure above the liquid decreases. Immediately, bubbles of CO₂ rapidly exit the solution and escape out of the top of the open bottle. If the bottle is left open for an extended period of time, the beverage becomes 'flat' as more and more CO₂ comes out of the liquid.
