The Science Behind Matchsticks
Matchsticks are one of the most commonly used tools in households and industries. They are tiny sticks made of wood or cardboard that ignite when rubbed against a rough surface. But have you ever wondered what the shelf life of a matchstick is? Let’s dive deep into the science behind matchsticks and understand how long they last.
What are Matchsticks Made of?
Matchsticks are made of a combination of different chemicals. The first component is the ignition source, which is usually red phosphorus. The second component is the fuel, which is typically made of sulfur and potassium chlorate. These chemicals are mixed with a binder and molded onto a wooden or cardboard stick. It is this mixture that makes matchsticks combustible.
Factors That Affect Shelf Life
Several factors come into play when it comes to the shelf life of matchsticks. These factors include humidity, temperature, and exposure to sunlight. Humidity can cause the matchsticks to absorb moisture, making them difficult to ignite. Extreme temperatures can cause the chemicals in the matchstick to break down, making them ineffective. Prolonged exposure to sunlight can also cause the matchstick to become brittle or even burst into flames spontaneously.
How Long do Matchsticks Last?
The shelf life of a matchstick can vary depending on the manufacturer and the storage conditions. Generally, matchsticks have a shelf life of around two years if stored in a dry and cool place. However, if the matchsticks are stored in a damp or humid environment, their shelf life can reduce to a few months.
In conclusion, the shelf life of a matchstick can be affected by numerous factors, including humidity, temperature and exposure to sunlight. Therefore, it’s important to store matchsticks in controlled environments to ensure their longevity. Even though matchsticks have a relatively short shelf life compared to other household items, they remain an essential tool in our daily lives.
