Solution

Ignition temperature is the lowest temperature at which a substance catches fire.
When a substance catches fire at a temperature lower than its ignition temperature is called combustion.
If a fuel has an ignition temperature lower than the average room temperature, combustion will occur suddenly on its own.
Such a combustion is known as spontaneous combustion.
