Answer:
Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products.[1] Slower oxidative processes like rusting or digestion are not included by this definition.
Fire is hot because the conversion of the weak double bond in molecular oxygen, O2, to the stronger bonds in the combustion products carbon dioxide and water releases energy (418 kJ per 32 g of O2); the bond energies of the fuel play only a minor role here.[2] At a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma.[3] Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different.
Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems.
The negative effects of fire include hazard to life and property, atmospheric pollution, and water contamination.[4] If fire removes protective vegetation, heavy rainfall may lead to an increase in soil erosion by water.[5] Also, when vegetation is burned, the nitrogen it contains is released into the atmosphere, unlike elements such as potassium and phosphorus which remain in the ash and are quickly recycled into the soil. This loss of nitrogen caused by a fire produces a long-term reduction in the fertility of the soil, but this fecundity can potentially be recovered as molecular nitrogen in the atmosphere is "fixed" and converted to ammonia by natural phenomena such as lightning and by leguminous plants that are "nitrogen-fixing" such as clover, peas, and green beans.
Fire has been used by humans in rituals, in agriculture for clearing land, for cooking, generating heat and light, for signaling, propulsion purposes, smelting, forging, incineration of waste, cremation, and as a weapon or mode of destruction.

A house on fire
On the evening of last Saturday, we were having a tea party in our house. All of a sudden, the happy atmosphere of the party was disturbed by a loud noise. The guests in the party started running out of the house in a great confusion. I came outside, and found that the one of our neighbor had caught fire. The flames were rising high up towards the sky. Everybody feared that a big fire would spread in the whole colony. We got anxious to bring the fire under control. The wind fanned the flames. People want to put out the fire with buckets full or water and bags of sand.
The lady of the house was weeping bitterly. Her cries were heart rending. Her only son was sleeping on the upper story. The fire had not yet reached there. But cloud of smoke were summing out of the window of that room. Going to that story to save the boy meant sure death. I wanted to rush to the help of the injured boy but I had injured leg. A young boy offered to risk his life. The people put a ladder against the wall. The boy ran up like an arrow. He brought down the child out of the flames. Both the boy and the child were choked with smoke.

The fire began to die down. It took two hours to bring it down. The building was reduced to ashes. It was a terrible sight. Our neighbor was in great distress. None could say how the fire broke out. Some said that the fire was started by some mischievous people in the colony. Other said that it was due to the carelessness of the servant of the house who left a burning cigarette near some clothes. In any case, the owner of the house suffered a heavy loss. But god be thanked there was no loss of life. Everyone praised the young boy of his bravery.
