What is Fire?

 Q1) WHAT IS FIRE?
ANS) FIRE IS THE VISIBLE PROCESS OF CHEMICAL REACTION (COMBUSTION REACTION) BETWEEN OXYGEN IN THE AIR AND ANY COMBUSTIBLE MATERIAL (FUEL) RELEASING HEAT.

 Q2) WHAT ARE THE ELEMENTS INVOLVED IN FIRE?
ANS)  THEY ARE THREE ELEMENTS INVOLVED IN FIRE
• SOLID LIQUID OR GAS COMBUSTIBLE MATERIAL ALSO CALLED FUEL,
• OXYGEN TAKEN FROM SURROUNDING AIR,
• HEAT

Q3) WHAT IS FIRE TRIANGLE?
ANS)  THEY ARE THREE ELEMENTS INVOLVED IN FIRE
• SOLID LIQUID OR GAS COMBUSTIBLE MATERIAL ALSO CALLED FUEL,
• OXYGEN TAKEN FROM SURROUNDING AIR,
• HEAT
THESE THREE ELEMENTS ARE CALLED FIRE TRIANGLE, WHICH is REPRESENTED AT THE SIDES OF TRIANGLE


Q4) WHAT IS DIFFERENCE BETWEEN STARTING OF FIRE AND PROPAGATION OF FIRE
ANS)   1 ) FIRE STARTS WHEN HEAT ENERGY IN THE FORM OF IGNITION (SPARK, FLAME) STARTS A CHEMICAL REACTION BETWEEN OXYGEN IN THE AIR AND COMBUSTIBLE  MATERIAL (FUEL). THIS IS CALLED FIRE STARTING OR FIRE INITIATION.

2) AFTER FIRE STARTS THE CHEMICAL REACTION BETWEEN OXYGEN AND FUEL GENERATES HEAT, WHICH PROVIDES THE REQUIRED TEMPERATURE TO CONTINUE REACTION BETWEEN OXYGEN AND FUEL, THIS IS CALLED FIRE PROPAGATION
