What is Fire?

The video explores the nature of fire, explaining why gas flames are blue and wood fires are orange. It delves into the physics of flames, discussing clean and impure flames, and the role of quantum mechanics. The concept of black-body radiation is introduced to explain why hot objects glow. The video also covers how gravity shapes flames, contrasting flame behavior in normal and zero gravity environments.
