TED-ED: The law of conservation of mass - Todd Ramsey

The video explores the origin and transformation of atoms, starting with the Law of Conservation of Mass, which states that mass cannot be created or destroyed. It demonstrates chemical reactions, such as the formation of water and carbon dioxide, and explains how energy is stored and released. The video also covers combustion reactions with methane and propane, emphasizing the conservation of atoms. Finally, it traces the origin of atoms back to the Big Bang, explaining how stars formed heavier elements and scattered them across the universe, leading to the formation of Earth and life.

What happens to the mass of atoms during nuclear reactions in stars, and how does this relate to energy?

Discuss the origin of the atoms that make up the Earth and living beings.
