Question

Why when the match stick on striking gives a sparkle and the match stick lights.

Answer 1

Answer:

When you rub the head of the matchstick on the striking surface of the matchbox, some heat is generated due to the friction. This heat breaks a small part of the red phosphorus chain. After that some red phosphorus transforms into white phosphorus. White phosphorus is a highly volatile chemical and ignites in the air.

Explanation:

$\huge\mathcal\pink{please}$   $\huge\mathcal\pink{drop}$   $\huge\mathcal\pink{some}$   $\huge\mathcal\pink{thanks}$   $\huge\mathcal\pink{dear.}$

$\huge\mathcal\red{I}$   $\huge\mathcal\red{will}$   $\huge\mathcal\red{return}$   $\huge\mathcal\red{you}$   $\huge\mathcal\red{back.}$

Answer 2

Answer:

The striker on a match pack or box also contains glass powder and sand, in addition to red phosphorus. The glass powder and sand provide friction that helps create the heat needed to turn a bit of the red phosphorus into white phosphorus, which is more volatile and ignites more easily.
