Chapter 25, Problem 66E
The density of air is generally given as mass per unit volume—for example, kilograms per cubic meter (kg/m3). Compare the following two dry air parcels at the same elevation: Air parcel 1 has a temperature of 32°F; and air parcel 2 has a temperature of 77°F. Which air mass is more dense? Explain.

Assume that the composition of the earth’s atmosphere is constant below an altitude of 100 km and according to Barometric equation, the pressure decreases with altitude and the atmosphere has a uniform temperature of 25°C. Calculate the barometric pressure in Pa at Mount Ağrı, for which h = 5137m (g = 9.80 m/s2). Assume that 80% of the air is nitrogen and 20% is oxygen.
Can the temperature ever rise with altitude in the real atmosphere?Wouldn’t this cause the air pressure to increaseupward? Explain the physics of this situation.
The middle ear has a volume of about 6.0 cm3 when at a pressure of 1.0 ×10^5 N/m^2.
Determine the volume of that same air when the air pressure is 0.83 × 10^5 N/m^2, as it is at an elevation of 1500 m above sea level (assume the air temperature remains constant).
