Questions and Answers
When a refrigerated bottle of carbonated beverage has not yet been opened, it feels rigid. When the carbonated beverage is opened, the container is no longer rigid, and an audible hiss is heard. Assume the gases involved in the carbonation of beverages are ideal. Which of the following is TRUE about the gases involved in carbonating the beverage?
When a refrigerated bottle of carbonated beverage has not yet been opened, it feels rigid. When the carbonated beverage is opened, the container is no longer rigid, and an audible hiss is heard. Assume the gases involved in the carbonation of beverages are ideal. Which of the following is TRUE about the gases involved in carbonating the beverage?
- The volume of the gas above the beverage solution increases upon opening the container.
- The temperature of the gas above the beverage solution decreases upon opening the container.
- The partial pressure of the gas above the beverage solution decreases to atmospheric pressure upon opening the container. (correct)
- The number of gas particles above the beverage solution remains constant upon opening the container.
What happens to the rigidity of the container when the carbonated beverage is opened?
What happens to the rigidity of the container when the carbonated beverage is opened?
- The container becomes more rigid.
- The rigidity of the container remains unchanged.
- The container is no longer rigid. (correct)
- The rigidity of the container increases and then decreases.

Dalton's Law of Partial Pressures
Dalton's Law of Partial Pressures
The force exerted by each gas component in a mixture is independent of other gases.
Why does a sealed carbonated beverage feel rigid?
Why does a sealed carbonated beverage feel rigid?
The container feels rigid due to the high pressure of dissolved carbon dioxide gas.
What happens to the container after opening a carbonated beverage?
What happens to the container after opening a carbonated beverage?
When opened, the pressure of dissolved carbon dioxide decreases to atmospheric pressure, causing the container to lose rigidity.

Study Notes
Carbonation of Beverages
- Before opening, a refrigerated bottle of carbonated beverage feels rigid due to the pressure of the carbon dioxide gas.
- When the carbonated beverage is opened, the container is no longer rigid.
- An audible hiss is heard when the carbonated beverage is opened, indicating the release of pressure.
Changes in the Gas Above the Beverage Solution
- When the container is opened, the volume of the gas above the beverage solution increases.
- The gas expands and occupies more space as the pressure is released.
Temperature of the Gas
- When the container is opened, the temperature of the gas above the beverage solution remains constant, assuming the gases involved in carbonation are ideal.
- The ideal gas assumption means that the temperature of the gas does not change during the process.
