If we put kerosine oil into a ash than it catches fire but when we put kerosine oil into a mud (soil) it will

Question

it will not catches fire why it so ???

Answer 1

Well, I am not a chemist. If I had to take a stab at this I would GUESS it's because the ash is dry and not very absorbent and the kerosene is still able to give off enough fumes to be ignited. However, the soil is moist and can absorb more of the fuel in such a matter than there aren't enough fumes to be easily ignited.

That's a guess. I have never actually encountered what you are describing.
