Actually, while it does convert energy into light energy, what interests most (to light a fire, for example) is the heat energy.
To answer your question, "why", that's because that's what it was designed to do.
If you mean "how" - basically, in energy terms, there is some chemical energy stored in the match. When the match burns, this is released as heat (and light, and some sound).
The energy transfer diagram for a match would show chemical potential energy being converted to thermal energy through combustion when the match is struck and ignites. The thermal energy produced then creates light energy and heat energy as the match continues to burn.
Chemical energy, stored in the match.
A match has chemical energy stored in the match head from the chemical reaction between the matchstick material and the phosphorus compound. When struck, this chemical energy is converted into heat and light energy through combustion.
A match burning is an example of chemical energy transitioning to light and heat energy.
The stick of a match contains chemical energy, which is released when the match is struck, causing a chemical reaction that produces heat and light.
Fu*king donkeys
Initially, chemical energy. This is converted mainly to heat, and some light.
chemical to light to heat energy :)
The total amount of energy remains constant, but it is transformed from chemical energy in the match head to thermal energy (heat) and electromagnetic energy (light) when the match is lit. This is an example of energy conservation in a closed system.
When striking a match, the chemical energy stored in the match-head is transformed into heat and light energy.
There is a very small amount of kinetic energy in striking the match, but mostly you are releasing chemical potential energy. The match head just requires an increase in temperature to make it burn
When a match burns, the chemical energy stored in the match head is converted into heat and light energy through a combustion reaction. This process releases energy in the form of heat and light, allowing the match to ignite and burn.
