At the surface of Venus the average temperature is a balmy 460 ∘C due to the greenhouse effect (global warming!), the pressure is 92 Earth-atmospheres, and the acceleration due to gravity is 0.894 gEarth. The atmosphere is nearly all CO2 (molar mass 44.0g/mol) and the temperature remains remarkably constant. We shall assume that the temperature does not change at all with altitude. Part AWhat is the atmospheric pressure 2.00 km above the surface of Venus? Express your answer in Earth-atmospheres. Express your answer using two significant figures. P = Earth atmPart BWhat is the atmospheric pressure 2.00 km above the surface of Venus? Express your answer in Venus-atmospheres. Express your answer using two significant figures. P = Venus atmPart CWhat is the root-mean-square speed of the CO2 molecules at the surface of Venus and at an altitude of 2.00 km ?vrms = m/s
