Burning of a matchstick is an example of :A.slow combustionB.ideal combustionC.rapid combustionD.spontaneous combustion

The burning of a matchstick is an example of C. Rapid Combustion.

Here's why:

Combustion is a chemical process in which a substance reacts with oxygen to give off heat. The combustion can be classified into different types based on its rate.

A. Slow Combustion: In this type of combustion, the substance burns slowly in the presence of air, and the reaction is slow. An example is the burning of coal.

B. Ideal Combustion: This is a theoretical concept and refers to the complete combustion of a fuel in which it burns completely and produces only carbon dioxide and water, with no other by-products.

C. Rapid Combustion: In this type of combustion, the substance burns rapidly and produces heat and light. The burning of a matchstick falls into this category because it burns quickly and produces heat and light.

D. Spontaneous Combustion: This type of combustion occurs when a material ignites without the application of external heat. An example is the spontaneous combustion of oily rags.

So, the correct answer is C. Rapid Combustion.
