The ideal gas law describes relationships among pressure, volume, temperature, and amount of gas under idealized conditions, but Earth’s atmosphere is also acted on by gravity. This video shows why temperature changes alone predict the wrong pressure at altitude and why the observed atmospheric pressure gradient requires the effect of gravity.
