Candle is a common burner, which usually consists of wax and fuel. When candles burn, they produce smoke and new substances. First, let's learn about the structure of candles. Candles generally consist of wick and wax. Wick is a kind of fiber or cotton thread that passes through the wax core and guides the flame when burning. Wax is usually a mixture made of petroleum, beeswax or other synthetic materials. When a candle burns, the flame will melt the surface of the wax, producing smoke and new substances.
Smoke is composed of unburned substances and tiny wax particles. These substances include carbon, hydrogen, oxygen, nitrogen and other elements, which come from the fuel and wax in candles. During the burning process, the fuel in the candle will react with oxygen to produce energy and new substances. These substances include carbon dioxide, water vapor and some organic compounds that are not completely burned. These substances are released into the air with smoke, which has an impact on the environment.
Carbon dioxide is a major greenhouse gas, which can absorb and release infrared rays, causing the earth's temperature to rise. Water vapor is also a greenhouse gas, but its influence on the earth's temperature depends on its concentration and temperature in the air. Some unburned organic substances may be harmful substances, such as polycyclic aromatic hydrocarbons and other carcinogens, which will have an impact on human health.
In short, when a candle burns, it will release smoke and new substances, including carbon dioxide, water vapor and some organic compounds that are not completely burned. These substances have a certain impact on the environment and human health. Therefore, we should reduce the use of candles and other burners to reduce the negative impact on the environment and human health.
The substances produced by candle burning include carbon dioxide, water vapor and some organic compounds that are not completely burned. Specifically, the fuel (such as oil) in the candle reacts with oxygen. In addition, candles also produce smoke, including unburned substances and tiny particles of wax. These substances will have a certain impact on the environment. In a word, we should reduce the use of candles and other combustibles to reduce the negative impact on the environment and human health.
