Fire as thermal conduction, convection, and radiation.

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

At the end there he just casually mentions how he witnessed a burning car exploding like it is a totally relatable event we all have experienced.

This guy teaches so well, he should have a website of his own where he teaches every subject in school.

Let say I am boiling an egg.


Heat from stove flame to pan = conduction
Heat from pan to water = convection

How about heat from boiling water to an egg? It is a conduction or convection?

good summary, but @ 7:10 ... the blue light is emitted because of chemical reactions and not because of incandescence. to see incandescent blue light from an object it has to be around 10000K. When a flame is blue it has around 1000K. The flame is the hottest where it's yellow-whiteish which is around 1800K...
