This actually happens in Winter. But they are so fucking euphemistic that winter has to be removed from the calendar.

For scales from absolute 0 like Kelvin, is proportional to the total kinetic energy of the material.

The Boltzmann constant tells us how much energy that is, i.e. gives the slope.

Same remarks as Section "Exam".

Definition not very nice, as it excludes X-ray crystallography, which is also photon based.
