Question

1. Estimate the following for a nitrogen molecule. The diameter of a nitrogen molecule is approximately 0.300 nm.

Estimate the mean free path of a nitrogenmolecule in air at the top of Mt. Everest (altitude = 8.80 km, P ≈ 50.0 kPa, and T ≈ 238 K). Value of Boltzmann's constant is 1.381×10⁻²³ J/K (answer is in nm)

3. A tank of compressed air of volume 1.00 m³ is pressurized to 27.0 atm at T = 273 K. A valve is opened, and air is released until the pressure in the tank is 13.4 atm. How many molecules were released? Boltzmann constant is 1.38 × 10⁻²³ J/K.
