Why is carbon dioxide commonly used?

1) As a greenhouse gas
2) In fire extinguishers
3) In carbonated beverages

Answer 1

Carbon dioxide is commonly used as a greenhouse gas, in fire extinguishers, and in carbonated beverages.

Step-by-step explanation:

Carbon dioxide is commonly used for various purposes due to its unique properties. Here are the three common applications:

1. As a greenhouse gas: Carbon dioxide is the primary greenhouse gas emitted through human activities, contributing to global warming. It is naturally present in the atmosphere but human activities, such as burning fossil fuels, are increasing its concentration.
2. In fire extinguishers: Carbon dioxide is commonly used in fire extinguishers as it displaces oxygen, reducing the oxygen concentration and smothering the fire.
3. In carbonated beverages: Carbon dioxide gas is dissolved in carbonated beverages, such as sodas, beer, and sparkling wines, which creates the fizz and enhances the drinking experience.
