One way to cool a gas is to let it expand. When a certain gas under a pressure of 5.00 106 Ha at 25.0C is allowed to expand to 3.00 times its original volume, its final pressure is 1.07 106 Pa.

The law of atmospheres states that the number density of molecules in the atmosphere depends on height y above sea level according to nV(y)=n0en0gy/kaT where n0 is the number density at sea level (where y = 0). The average height of a molecule in the Earths atmosphere is given by yavg=0ynV(y)dy0nV(y)dy=0yen0gy/kaTdy0en0gy/kaTdy (a) Prove that this average height is equal to kBT/m0g. (b) Evaluate the average height, assuming the temperature is 10.0C and the molecular mass is 28.9 u, both uniform throughout the atmosphere.
