Chapter 10, Problem 65EAP

Escape from Venus.

  1. Calculate the escape velocity from Venus’s exosphere, which begins about 200 kilometers above the surface. (Hint: See Mathematical Insight 4.4.)
  2. Calculate and compare the thermal speeds of hydrogen and deuterium atoms at the exospheric temperature of 350 K. The mass of a hydrogen atom is  1.67 × 10 27 kilogram, and the mass of a deuterium atom is about twice the mass of a hydrogen atom.
  3. In a few sentences, comment on the relevance of these calculations to the question of whether Venus has lost large quantities of water.

Solar scientists want to measure the temperature inside the sun by sending in probes. Imagine that temperature increases by 1 million◦C for every 10,000 km below the surface. A probe that can handle a temperature of x million degrees costs x³ million dollars. a. How much would it cost to measure the temperature 10,000 km down? b. How much would it cost to measure the temperature 100,000 km down? c. How much would it cost to measure the temperature 200,000 km down?
CO2 and planetary warming: understanding Earth’s complicated atmosphere Mars has an atmospheric pressure of 6 mbar (compared with Earth atmosphere pressure of 1013 mbar), 96% of which is CO2. The average calculated temperature of Mars is -57°C, whereas the actual average temperature is -55°C so that the amount of warming due to CO2 is only 2°C. On the other hand, the average calculated temperature of Earth, with 0.4 mbar of CO2, is -19°C, whereas the actual average temperature is 15°C so that the amount of warming due to CO2 is 34°C, much greater than that on Mars, which has higher CO2 concentration. Explain how this is possible.
What is the runaway greenhouse effect, and how might it have altered the climate of Venus?
