Fire is an example of an exothermic reaction, because heat is released from the system.
To understand why fire is considered an exothermic reaction, let's first define what an exothermic reaction is. In chemistry, an exothermic reaction is a chemical reaction that releases energy in the form of heat. This means that the reaction causes the surroundings to become warmer.
In the case of fire, the reaction involves the combustion of a fuel (such as wood or gasoline) in the presence of oxygen. When the fuel combines with oxygen, a chemical reaction takes place, resulting in the release of energy in the form of heat and light. This heat is what we perceive as the flames and the warmth that radiates from the fire.
So, to summarize, fire is an example of an exothermic reaction because it releases heat energy into the surroundings.
