Why is carbon dioxide gas rapidly released from a soda water bottle when it is opened?

Options

ATo increase its temperature
BTo decrease its pressure
CTo reach a new equilibrium with the lower pressure of the atmosphere
DTo decrease its solubility

Correct answer

C. To reach a new equilibrium with the lower pressure of the atmosphere

Step-by-step solution

When a soda water bottle is opened, some of the dissolved carbon dioxide gas escapes to reach a new equilibrium with the lower pressure of the atmosphere.
