It is hard to ignite match stick in rainy days. Why
Answers
Matchsticks consist of a head and a wooden stick. The head contains potassium chlorate, an oxidizing agent, a small quantity of powdered glass that provides the essential friction while striking. The other part is the striking surface, which mostly consists of red phosphorus, powdered glass (or silica), binder and filler.
When we rub the stick against the striking surface, the friction generated causes some of the red phosphorus present to turn into white phosphorus. White phosphorus is highly volatile. It ignites spontaneously in the air, making a flame. It burns up the length of the wooden stick in the presence of atmospheric oxygen.
But on a rainy day because of the high level of moisture present in the atmosphere it becomes hard to ignite a match stick.
it is hard to Ignite matchstick in rainy days because water has extinguishing property.
