WebAug 31, 2024 · How does density of air affect atmospheric pressure? The air is compressed. The density increases as pressure increases. Altitude and weather systems can change the air’s pressure. As you go higher, the air’s pressure decreases from around 1,000 millibars at sea level to 500 millibars at around 18,000 feet. WebFeb 24, 2024 · p ρ = constant × T. The ratio of pressure to density, and therefore the speed of sound in air, depends just on the temperature. If you double the pressure you put on a sample of air (as long as you don't let its temperature change), you double its density and therefore leave the speed of sound unchanged. Note that this applies to any one gas.
