From the ideal gas law,

$\overline{){\mathbf{P}}{\mathbf{V}}{\mathbf{=}}{\mathbf{n}}{\mathbf{R}}{\mathbf{T}}}$, we see that temperature is directly proportional to the pressure and volume of the gas.

Volume is given by:

$\overline{){\mathbf{V}}{\mathbf{=}}\frac{\mathbf{m}}{\mathbf{\rho }}}$

This implies that volume is inversely proportional to density.
