Have you seen a fire or flame? If not, observe the fire in the picture below. http://www.redpix.com/p/4477/camp-fire-camphite camping nature campfire-surwet-outdoor andre How does fire start? Will fire continue its flame in the absence of oxygen? Suppose we will cover it with a basin, what do you think will happen to the fire? What are the three important things needed for combustion to occur?​

Answer:

• HOW DOES FIRE START? - Fires start when a flammable or a combustible material, in combination with a sufficient quantity of an oxidizer such as oxygen gas or another oxygen-rich compound (though non-oxygen oxidizers exist), is exposed to a source of heat or ambient temperature above the flash point for the fuel/oxidizer mix.

• WILL FIRE CONTINUE ITS FLAME IN THE ABSENCE OF OXYGEN? - Without sufficient oxygen, a fire cannot begin, and it cannot continue. With a decreased oxygen concentration, the combustion process slows. Oxygen can be denied to a fire using a carbon dioxide fire extinguisher, a fire blanket or water.

• SUPPOSE WE WILL COVER IT WITH A BASIN, WHAT DO YOU THINK WILL HAPPEN TO THE FIRE? - The fire will stop being fueled to burn more because oxygen it's gas is depleted.

• WHAT ARE THE THREE IMPORTANT THINGS NEEDED FOR COMBUSTION TO OCCUR? -

The three important things needed for combustion to occur are the following;

There must be Fuel to burn.

There must be Air to supply oxygen.

There must be Heat (ignition temperature) to start and continue the combustion process
