ng answer questIonShor carhon dioxide is used to extinguish fires with the help of fire estingsishers |
|
Answer» Fires need oxygen, fuel, and heat to ignite, and removing any one of those three components can put out a fire. Carbon dioxide extinguishers work because carbon dioxide molecules are heavier than oxygen molecules. When the liquid carbon dioxide inside the extinguisher expands into a gas, the carbon dioxide pushes out any oxygen surrounding the fire. Without oxygen available to fuel the chemical reaction, the fire goes out quickly. |
