ignite
to catch on fire
When something catches on fire, it means that it ignites and starts to burn. Fire is a chemical reaction that occurs when a substance combines with oxygen, producing heat and light. For something to catch on fire, it needs three things: heat, fuel, and oxygen. If these three elements combine in the right amounts, a fire can start.
Heat is the first element needed for a fire. Heat can come from a variety of sources, such as a flame, a spark, friction, or even the sun. When heat is applied to a fuel source, it causes the molecules in the fuel to move faster and become more unstable.
Fuel is the second element needed for a fire. Fuel can be any material that can burn, such as wood, paper, gasoline, or propane. When fuel is heated, it releases gases that combine with oxygen in the air to cause a chemical reaction that produces a flame.
Oxygen is the third and final element needed for a fire. Oxygen is all around us in the air we breathe. When oxygen combines with the gases released from the fuel, it creates a chemical reaction that produces heat and light.
In summary, for something to catch on fire, it needs heat, fuel, and oxygen. If these three elements combine in the right amounts, a fire can start. It is important to take proper precautions when working with potential fire hazards to prevent accidental fires. It is also important to know how to safely extinguish a fire in case one does occur.
