This thing has me curious. I just found this little tidbit. See what you
think.

It comes from the work done compressing the gas in the cylinder.

The Temperature changes in response to compression due to addition of
more molecules of air to the closed, fixed-volume cylinder. Work is
produced. Temperature rises.

The temperature must change by following Ideal Gas Law:

P V = N k T

Where P = pressure, V = volume, N = number of gas molecules, k = is
Boltzman's constant and T is Kelvin.

The equation must balance. Pick any system of gasses at a specific
pressure, temperature and volume. Change any of those four conditions,
the others must change proportionately.

But temperature *is* a measure of energy.

It is a partial measure of energy. It doesn't measure potential energy.
