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 A
What is the atmospheric pressure 4.00 km above the surface of Venus? Express your answer in Earth-atmospheres.
Express your answer using two significant figures.
Part B
What is the atmospheric pressure 4.00 km above the surface of Venus? Express your answer in Venus-atmospheres.
Express your answer using two significant figures.
Part C
What is the root-mean-square speed of the CO2 molecules at the surface of Venus and at an altitude of 4.00 km ?

    2. Atmospheric Mass Venus and Earth have about the same mass and radius, but the atmospheric pressure on the surface of Venus is measured to be 90 times larger than the pressure at the surface of the Earth. (a) Assuming Venus' atmosphere is pure CO2 and Earth's atmosphere is pure N2, estimate the atmospheric scale height for each planet. For simplicity you can assume that both atmospheres are isothermal with T = 550 K for Venus and T = 250...

    Part A The tire is inflated (while cold) to a volume of 11.8 L and a gauge pressure of 36.0 psi (Note: The gauge pressure is the difference between the total pressure and atmospheric pressure. In this case, assume that atmospheric pressure is 14.7 psi.) at a temperature of 12.0° C. While driving on a hot day, the tire warns to 65。°C and its volume expands to 12.2 L. What is the total pressure (gauge pressure+ atmospheric pressure) in the...

    Could Venus have ever had liquid oceans? Calculate its surface temperature (w/o greenhouse) using the fact that the Sun was 30% dimmer 4 by ago and Venus is at about 70% the Earth’s distance to the Sun. How does that result compare to the Earth at the present time? Explain your reasoning.

    Enter your answer in the provided box. Although the planet Venus is similar in size and composition to Earth, the carbon dioxide atmosphere at its surface is not conducive to life. The average temperature is about 740 K, and the atmospheric pressure is extremely high. If the atmospheric pressure is 95 atm, calculate the mass of atmospheric gas (assume it all to be carbon dioxide) in 2.7 L.

    1. For the earth, an estimate of the variation of pressure with altitude above the surface of the earth is made for a gas of molecular weight, M, assuming the atmosphere is isothermal, the variation of g with altitude is negligible, and that the atmosphere behaves like an ideal gas. A significant error in this estimate arises from the assumption that the temperature of the atmosphere, T, is isothermal instead of decreasing with altitude. This decrease with altitude y in...
