Fire
Do you know ? How Fire Produce?
Fire is a very essential thing in Our day today life. A simple Concepet is behind the formation of Fire. Formation of Frie is not a Independent process it is a dependet process. What is it depends, it is depends on three major things
Without the above Mentioned three things Fire won't rxist. That means, If any one of the above mentioned thing is absence fire won't exist.
Fire forms " If any BUrnable materials like Paper, Cotton, Wood, etc... in the presence of fuel gets heat"
Some examples that Support the above concept:
Eg: 1
A well Known example
When Focusing Sunlight Over a Paper, Or a Cotton through a lens it will burn. Do you know why it burn or Catch fire
paper-----------------> burnable material
Fuel------------------> Oxygen
What else we need to produce a fire. "HEAT" is the next thing
While focusing the Sunlight over a Paper it will produce Heat over the paper. So that Paper will Catch fire Easily.
Example; 2
A Chemical Experiment
Take Pottasium Permonganate Crystals in a Paper and pour Glycerin over that glycerin&
