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 light emission from 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, and the effect of gravity on flame shape is discussed, highlighting how flames behave differently in zero gravity.

What causes the different colors of flames, such as blue in gas flames and orange in wood fires?

Explain the concept of Black Body Radiation and how it relates to the glowing of hot objects.

Discuss the role of temperature in the color of light emitted by objects.

How does gravity influence the shape of flames?

What happens to a flame in a zero-gravity environment, and why does it behave that way?
