Re: [Phys-l] Temp & Energy density

Larger energy density implies increase in temp.

Simply not so. Others seem not to have directly addressed the central misconception here so allow me.

Example: For a monatomic ideal gas at equilibrium

PV = Nkt = (2/3)U

thus

energy density = U/V = (3/2)P

That is, energy density is directly proportional to equilibrium pressure and has no direct connection to temperature.
