Question

What is rapid combustion , spontaneous combustion and explosion combustion

Answer 1

Explanation:

1. Rapid combustion is a form of combustion in which large amounts of heat and light energy are released. This often occurs as a fire. This is used in a form of machinery, such as internal combustion engines, and in thermobaric weapons.

2. Spontaneous combustion is the phenomenon in which a hydrocarbon (or a chemical substance) substance unexpectedly bursts into flame without apparent cause. In ordinary combustion, the hydrocarbon is deliberately heated to its ignition point to make it burn.

3. The transition from combustion to explosion is caused by an acceleration of the reaction, induced either by a rise in temperature or by increasing lengths of the reaction chain. The first is called thermal explosion, and the second is called chain explosion

Answer 2

Answer:

1. the combustion burn rapidly by a flame is called rapid combustion . example : wood
2. the combustion which burn quickly is called spontaneous combustion
3. the sudden blast with the evaluation of heat, light and smoke is called explosion
