VERIFY THAT GAS WHOSE .024(a)&.027(b) WILL PRODUCE HEATING EFFECT AT 300K WHEN SUBJECTED TO ADIABATIC EXPANS.?

Joule thomson inversion temperature = 2a/Rb = 21.6 K .Above this temperature, during adiabatic expansion of gas from high pressure to low pressure the gas experiences heating. Below this temperature the gas experiences cooling. At Joule thomson inversion temperature the gas experiences neither cooling nor heating.
