Question

How should density evolve upon an increase in temperature of a gas?

Answer 1

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.
