What is Temperature?

MIT RES.TLL-004 Concept Vignettes
Instructor: Jeff Grossman

This video motivates the statistical mechanics approach through material structure and behavior. Entropy is introduced as a natural variable whose derivative with respect to energy is zero when the number of microstates is maximized.

Excellent! More people should know this.

Spoiler:

when two systems have the same temperature, the relative change in the number of microstates with energy is the same in both systems.

Wow great explanation! I really can't express how much I love MIT's courses on youtube. I use them to learn physics, math, chemistry and so on I love them. I myself am new to physics but I sure love all these lectures thanks a lot.

wow, brilliant explanation of entropy

All stuff is Heat and Freeze,
compositions of Heat and Freeze,
temperature is a condition of Heat and Freeze.

In this video, particles do interact.
