eal gas. 2. Molecules in the Earth's atmosphere. If n is the concentration of molecules at the surface of the Earth, M the mass of a molecule, and g the gravitational acceleration at the surface show that at constant temperature the total number of molecules in the atmosphere is (75) with r measured from the center of the Barth; here R is the radius of the Earth. The integral diverges at the upper linit, so that N cannot be bounded...

The escape speed from the Earth is 1.12×104m/s, so that a gas molecule travelling away from Earth near the outer boundary of the Earth's atmosphere would, at this speed, be able to escape from the Earth's gravitational field and be lost to the atmosphere. Part A At what temperature is the average speed of oxygen molecules equal to 1.12×10^4m/s? Part B At what temperature is the average speed of helium atoms equal to 1.12×10^4m/s?
