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. This derivative is identified as being the reciprocal of temperature, and Boltzmann’s constant is explained.
After watching this video students will be able to explain how the definition of temperature arises as a derivative of entropy with respect to energy.

It is highly recommended that the video is paused when prompted so that students are able to attempt the activities on their own and then check their solutions against the video.
During the video, students will:
