There's a law of thermodynamics that says otherwise.

Compressed air exiting an orifice gets colder (temperature decreases) from
expansion, while gaining some new heat from the friction and turbulence of
passing through the orifice. Which law of thermodynamics "says otherwise"?

Perhaps the one that sez Foreman maybe oughtta stick to electronics?

I've always thought of temperature as proportional to heat content in
joules or calories times specific heat of the material holding it.
