When heat released by a substance is higher than the heat required for ignition of the substance, then which of the given combustion occurs? Correct Answer spontaneous

Concept:

Combustion:

  • A chemical process in which a substance reacts with oxygen to give off heat is called combustion.
  • The substance that undergoes combustion is said to be combustible.
  • It is also called fuel.
  • The fuel may be solid, liquid or gas. 
  • Combustion reactions are exothermic since heat is generated during the process.

There are 3 types of combustion- rapid, explosion, and spontaneous.

Rapid combustion:

  • The type of combustion when gas burns rapidly and produces heat and light is known as rapid combustion.

Explosive combustion:

  • Explosion combustion is that in which a huge amount of gases are evolved with the production of a large amount of light and sound.

Spontaneous combustion:

  • Spontaneous combustion is that in which no external heat is provided.
  • When heat released by a substance is higher than the heat required for ignition of the substance is known as Spontaneous combustion.
