What are the uses of CO₂?
Carbon dioxide has many industrial and commercial applications. CO₂ is used for cooling (as dry ice) and refrigerating, in fire extinguishers (as it blocks fire from getting the oxygen it needs), for inflating life jackets, to create bubbles during foaming rubbers, plastics, and concrete, to preserve food in food packaging, in the production of carbonated soft drinks and alcohols with bubbles, and for helping the growth of plants in greenhouses (a process called CO₂ enrichment).
