18.54----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.
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. (answer cannot be 84 or 83.66 atm)
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. (answer cannot be 0.91 atm)
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...

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...

A cylinder contains 0.300 mol of carbon dioxide (CO2)gas at a temperature of 23.0 ∘C. The cylinder is provided with a frictionless piston, which maintains a constant pressure of 1.00 atm on the gas. The cylinder is placed on a hot plate and a 920 J of heat flows into the gas, thereby raising its temperature to 130 ∘C. Assume that the CO2 may be treated as an ideal gas. 1. What is the change in internal energy of the...
