Understanding the Science behind Matchsticks
Matchsticks are small but essential items used for ignition purposes. They are usually coated with a mixture of phosphorus and potassium chlorate, which catches fire when it comes into contact with oxygen. Although matchsticks are relatively easy to use, some people often face the challenge of lighting them up. Some of the reasons for this issue include dampness, poor storage conditions, and many others. However, one interesting phenomenon is when matchsticks sometimes bend when you try to light them, and here’s why:
The Role of Adhesion in Matchsticks
Adhesion is the force that allows two dissimilar substances to stick together. In the case of matchsticks, the wood is porous and therefore absorbs moisture from the environment. When this happens, the match head and the wooden stick become sticky, making it hard to light the matchstick. When you strike the matchstick, the adhesive between the wooden stick and the match head restricts movement and may cause the stick to bend rather than breaking or igniting.
The Impact of Atmospheric Pressure on Matchsticks
Atmospheric pressure is a measure of the weight of the Earth’s atmosphere above an object. It is a force that affects the success of lighting matchsticks. When the atmospheric pressure is high, the air’s density around the matchstick is also high, which affects the oxygen’s availability for combustion. Therefore, when you attempt to light the matchstick, you may notice that it takes longer or fails to light, causing the stick to bend under the increasing pressure.
The Chemical Composition of Matchsticks
The chemical composition of matchsticks plays a critical role in their ease of use. The mixture of phosphorus and potassium chlorate on the match head is responsible for igniting when you strike it against a rough surface. The quality and quantity of the chemicals used in making the matchstick influence how easy it is to light up. If the chemicals are not well mixed or are of low quality, lighting the matchstick may be difficult, causing the matchstick to bend.
The Need for Proper Storage of Matchsticks
Finally, proper storage of matchsticks is critical in maintaining their quality, making them easier to light up. Matchsticks need to be kept in a dry and cool place, away from excessive heat to prevent moisture and heat from interfering with their chemical composition. Failure to keep matchsticks in good storage condition can affect their ability to light up correctly. When using poorly stored matchsticks, striking the matchstick will become a challenge, ultimately causing it to bend under the pressure of the human hand.
