Interesting fact: Fire itself does not have mass, but the hot gases and particles it produces do.
The answer: A fire has no weight, but the smoke, hot gases, and ash it generates can weigh several kilograms to tons depending on the fire size.
Fire is a chemical reaction involving combustion, releasing heat and light. The flame itself is energy and plasma, which has no mass. However, the combustion process produces gases, smoke particles, and ash, which have mass and weight. The amount of these byproducts depends on the fuel and size of the fire. Understanding this distinction helps clarify common misconceptions about the physical properties of fire.
