At the surface of Venus the average temperature is a balmy 460 ∘C∘C due to the greenhouse effect (global warming!), the pressure is 92 Earth-atmospheres, and the acceleration due to gravity is 0.894 gEarthgEarth. The atmosphere is nearly all CO2CO2 (molar mass 44.0g/mol)g/mol) and the temperature remains remarkably constant. We shall assume that the temperature does not change at all with altitude.

(a) What is the atmospheric pressure 1.00 km above the surface of Venus? Express your answer in Venus-atmospheres and earth-atmospheres.
(b) What is the root-mean-square speed of the CO2 molecules at the surface of Venus and at an altitude of 1.00 km?
