WebPresence of humidity in air makes the condition hot and humid. Density of air (and air pressure) is less in places of high altitude. Hence, humidity does effect the density of air. WebThis tool calculates air density considering that these three parameters and at the same time shows a graph of density as a function of temperature. If we keep pressure constant, the higher the temperature, the lower the density. On the other hand, when pressure is increased the density is also higher, so at high altitudes density decreases.
