Question

What is Rapid combustion and
What is Ignition Temperature?​

Answer 1

Answer:

1) answer: 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) answer: The autoignition temperature or kindling point of a substance is the lowest temperature at which it spontaneously ignites in normal atmosphere without an external source of ignition, such as a flame or spark. ... The ignition temperature of a substance is the least temperature at which the substance starts combustion.

Answer 2

Combustion in which a substance burns rapidly and produces heat and flame is known as rapid combustion.

Example: combustion of LPG gas, petrol etc.

Substances which undergo rapid combustion have lower ignition temperature.
