Pressure on Venus. At the surface of Venus the aver-age 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 g earth . The atmosphere is nearly all CO 2 (molar mass 44.0 g/mol), and the temperature remains remarkably constant. Assume that the temperature does not change 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 CO 2 molecules at the surface of Venus and at an altitude of 1.00 km?

The number density of gas atoms at a certain location in the space above our planet is about 1.1 × 1011 m-3, and the pressure is 2.55 × 10-10 Pa in this region.
What is the temperature in this region, in degrees Celsius?
The atmosphere of the planet Mars is 95.3% carbon dioxide(CO2) and about 0.03% water vapor. The atmospheric pressure isonly about 600 Pa, and the surface temperature varies from -30C to-100C. The polar ice caps contain both CO2 ice and water ice. Couldthere be liquid CO2 on the surface of Mars? Could there be liquidwater? Why or why not?
