"WebAnswer: ISA Variation = ISA-8 . Air Density varies with Height. In the Standard Atmosphere, pressure height and density height at any one point are equal. As air warms up at constant pressure, it expands. This causes the air density to decrease, since there will be fewer air molecules per unit volume, yet the pressure height will remain unchanged.
