Temperature is not just heat, but a measure of entropy

What is Temperature? · 12:08 · Video: MIT OpenCourseWare · Watch at the source

In short: Most people view temperature as a simple feeling of hot or cold. This video explores the deeper statistical mechanics behind the concept, explaining how it relates to energy and the hidden behavior of microscopic states.

The video introduces temperature through the lens of material structure and behavior. It frames entropy as a natural variable that reaches its peak when the number of microstates in a system is maximized.

By examining the derivative of entropy with respect to energy, the presentation motivates a statistical mechanics approach to understanding how matter behaves at different scales.
