It is explosive combustion. because in explosive combustion heat, light, and sound is produced very quickly.
In which of the following types of combustion are heat, light and soun...
Explanation:
Rapid combustion:
In rapid combustion, heat, light, and sound are produced. This type of combustion occurs when a substance burns rapidly in the presence of oxygen. Examples of rapid combustion include burning of wood, paper, and candles. When these substances burn, they produce a large amount of heat, visible light, and sound.
Explosive combustion:
Explosive combustion is a type of combustion that occurs very rapidly, releasing a large amount of energy in the form of heat, light, and sound. It is characterized by a sudden release of gases and a rapid increase in pressure. Examples of explosive combustion include fireworks, detonations, and certain types of fuel explosions. In these cases, the rapid release of energy causes a loud sound, bright light, and intense heat.
Spontaneous combustion:
Spontaneous combustion is a type of combustion that occurs without an external ignition source. It happens when a substance self-heats due to internal chemical reactions, eventually reaching its ignition point and catching fire. Examples of spontaneous combustion include oily rags, compost piles, and coal dust. While heat and light are produced in spontaneous combustion, the sound produced is usually minimal or nonexistent.
Conclusion:
Out of the given options, only explosive combustion produces heat, light, and sound. Rapid and spontaneous combustion may produce heat and light, but sound production is not characteristic of these types of combustion. Therefore, the correct answer is option B (Explosive).
