The composition of the atmosphere is approximately 80 per cent nitrogen and 20 per cent oxygen by mass. At what height above the surface of the Earth would the atmosphere become 90 per cent nitrogen and 10 per cent oxygen by mass? Assume that the temperature of the atmosphere is constant at 25oC. What is the pressure of the atmosphere at that height?

Oxygen and Nitrogen are mixed adiabatically at 80°C. Oxygen has an initial volume of 20 meters cubed and a pressure of 100 bar. Nitrogen has a volume of 90 meters cubed and an initial pressure of 50 bar. If the system has no change in volume, calculate: Final pressure Mass AND mole fractions in % Entropy change of EACH gas

Review Constants Periodic Table Air consists mostly of nitrogen (N), with a molecular mass of 28, and oxygen (O2), with a molecular mass of 32. A water molecule (H,O) has molecular mass 18. According to the ideal gas law (N/ V P /KT), dry air at a particular pressure and temperature has the same particle density (number of particles per unit volume) as humidait at the same pressure and temperature. Consequently, humidair, whose low-mass water molecules replace more massive nitrogen...
