Oxygen is combustion-supporting, which can make the burning stick burn more violently.
Oxygen is one of the gases necessary to sustain life. It reacts with many organic compounds and has oxidation effect. When wood is ignited, oxygen reacts with combustible substances (such as lignin and cellulose) in the wood, converting carbon and hydrogen in the wood into carbon dioxide and water vapor, and releasing a lot of energy to keep the wood burning, so oxygen can make the burning stick burn more violently.
Besides making fuel rod burn more vigorously, oxygen has other characteristics and uses.
Oxygen is a colorless, odorless and nontoxic gas with a molecular weight of 32, which is one of the most abundant gases in the earth's atmosphere. Oxygen is an important substance for many organisms to breathe. Oxygen inhaled by humans and other animals reacts with hemoglobin in the blood in the lungs, and carbon dioxide is excreted, so that all organs of the body can get the needed nutrition.
In addition, oxygen can also be used in medical emergency, diving, aerospace, industrial production and other fields. In medical emergency, oxygen is one of the commonly used treatment methods for patients with respiratory diseases; In diving, oxygen is a necessary condition to ensure the diver's breathing and safety; In aerospace, oxygen is one of the necessary oxidants for aerospace vehicles. In industrial production, oxygen can be used in metal cutting, welding and other processes.
In a word, oxygen is a very important gas and plays an important role in life activities and industrial production.
