How does fire relate to physics?

Answer 1

While physics at it's most basic level, the actual burning of fire is typically considered to be chemistry. However the rising flames and their shape may easily be categorized as physics. It will also describe the heat transfer to fresh fuel, before that begins burning. The rising smoke from fire is even said to have inspired Daniel Bernoulli to create his physical principles of things like laminar flow.

Answer 2

Fire involves the transfer of heat energy, which is a fundamental concept in physics. The combustion process that sustains a fire involves chemical reactions that release energy, demonstrating principles of thermodynamics. Fire also emits light, which can be understood through the physics of electromagnetic radiation and the behavior of photons.
