Air is a ideal gas pv = mrt.

Density === p/t.

If t increase density decrease.

Wrong because if we change the height temperature will change further pressure will changes.

As we go above, from earth surface pressure decreases. As pressure decreases air expands thus density decreases.

p=(density)*g*h.

So, Density is inversely proportional to the height.
Height increases density decreases.

Density changes with height. At stratosphere the density of air is less than the surface.
