Well, the density should reasonably DECREASE..........

Explanation:

From the Ideal Gas equation.........

"mass"/"molar mass"=(PV)/(RT), agreed?

"mass"/"V"=(Pxx"molar mass")/(RT),

i.e. "mass"/"V"=rho("density")prop1/(T), or rho=k/T, where k, the constant of proportionality, ="molar mass"/RxxP.

And thus rho should vary INVERSELY with increasing temperature.
