Heat is not a substance but a movement of energy
In short: Most people treat heat as if it were a physical thing, like a fluid filling a room. This video clarifies the actual physics by defining heat as a specific type of energy transfer.
Presented by Dr. Edouard Reny, the video moves beyond common misconceptions to define heat (Q) precisely as a non-mechanical transfer of energy from an object at a higher temperature to one at a lower temperature.
To establish this foundation, the content first provides a rigorous definition of temperature before examining the microscopic behavior occurring at the contact interface between two solids. Understanding these interactions is essential for fields ranging from astrophysics and materials science to biology and geology.
