Matches are lit by friction. These work as the match heads contain sulphur and oxidising agents, with the surface of it consisting of powdered silica. As the striking surface, usually on the side of the match box, is also made up of powdered silca the glass-on-glass reaction generates heat. This causes the red phosphorous in the match head to turn into white phosphorous vapour which spontaneously combusts and starts burning the wood of the match.

What type of friction between air and another material called?
kinetic friction
What the value of abs plastic static friction coefficient?
With what material? Coefficient of friction is for two materials.
How surface influences the amount of friction there is?
The larger the contact surface, the more friction. The more uneven the surface, the more friction. The material of the surface has also an effect on friction.
What types of materials can cause friction?
Any type of material has friction because everything has microscopic hills and valleys; some materials have more friction because the materials hills and valleys are larger than other materials.
When friction occurs?
Friction occurs when two material bodies in contact slide past one another.
Could you use wood for static friction?
Wood, or any other material, could be used to introduce static friction to a system. The choice of material(s) depends on how much static friction the system requires. Each material has its unique coefficient of friction.
What type of friction between air and another material called?
kinetic friction
What is a pyrophoric scale?
Pyrophoric scale is a material that can be burnt or ignited spontaneously when in contact with air, if struck or scratched.
What the value of abs plastic static friction coefficient?
With what material? Coefficient of friction is for two materials.
How surface influences the amount of friction there is?
The larger the contact surface, the more friction. The more uneven the surface, the more friction. The material of the surface has also an effect on friction.
What types of materials can cause friction?
Any type of material has friction because everything has microscopic hills and valleys; some materials have more friction because the materials hills and valleys are larger than other materials.
Why do materials have different coefficient of friction?
Different materials have different coefficients of friction because the materials have different microscopic bumps and valleys which cause the friction to begin with. Coefficients of friction are constant for each material.
What is a material like grease which reduces friction?
Graphite
When friction occurs?
Friction occurs when two material bodies in contact slide past one another.
What are ceramics in modern cars?
The friction material in the braking system
What happens to coefficient of friction when surfaces get hot?
It depends on the material.
How do material become charged?
by rubbing(or friction) by contact by induction
