Question

combustion is of........type​

Answer 1

$\huge {\bf{\red{Types \:</p><p>of\: Combustion}}}$

Combustion can be divided into the following three types:

$\bf{\underline{\underline{1. \:Rapid\: Combustion : }}}$

When large amount of heat and light are produced in very short span of time, it is called rapid combustion.) For example, combustion of LPG.

$\bf{\underline{\underline{2.\: Spontaneous Combustion: }}}$

When a material suddenly bursts into flames, without the application of any apparent cause (heat), it is called spontaneous combustion. For example, white phosphorus burns in air at room temperature without application of heat.

$\bf{\underline{\underline{3.\: Explosion:}}}$

When a material bursts by sudden release of heat, light and sound accompanied by the liberation of a large amount of gas in the reaction, it is called explosion. Explosion can also take place if pressure is applied.

Answer 2

Explanation:

Four types of combustion:-

Slow combustion

Combustion takes place slowly due to insufficient supply of oxygen

e.g burning of wood

Rapid Combustion

Combustion that take place rapidly

e.g burning of LPG

Spontaneous Combustion

Combustion that takes place spontaneously

e.g White phosphorus burns spontaneously while kept in open atmosphere

Explosive Combustion

Combustion which produces explosive sound

e.g burning of crackers
