density temperature dependence

Can someone explain density and temperature dependence for solids, liquids, and gases from a physics perspective or using an equation?

I am thinking for gases it would be (P*MW)/(RT) = rho? Is this the right way to look at it?

Not sure what equation for solids/liquids to use? Volumetric expansion in M/V = rho?

Thanks!

You dont need any equations for it.
Solids, liquids, and gases expand when temperature increases.
Since mass does not change, density = m/v decreases.
