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.

What are the differences in color between gas flames and wood fires, and what causes these differences?

Explain the concept of black-body radiation and how it relates to the color of glowing objects.

Why do we not see our friends glowing, and what type of light do we actually emit?

How does gravity affect the shape of flames, and what happens to a flame in zero gravity?

What role does convection play in the behavior of flames?
