Question

how does a matchstick catch fire when rubbed on the rough surface of the box ?
$please \: solve \: this$

Answer 1

Stored inside the match head is another chemical called “potassium chlorate”. When it gets hot, it releases a lot of extra oxygen and heat. This makes the match head burn quickly and strongly. When you put it all together – the heat, the fuel, and the oxygen – you get a flame!

Answer 2

On rubbing the matchstick on the rough surface, the friction converts this work into heat. The heat raises the chemical present on the matchstick head to its ignition temperature. Due to this, the chemical substance catches fire and the matchstick starts burning.
