The atmosphere of Mars is almost all carbon dioxide and the average surface pressure is 610 Pa (as compared with 101,000 Pa on Earth). A model for the temperature in the atmosphere is given by: $T = T_0e^{-Cz}$, where $C = 1.1E – 5 m^{-1}$ and $T_0 = 250K$. The gravitational acceleration is $g = 3.71 m/s^2$. Assume ideal gas behavior. Determine: a. analytic equation for the variation of pressure with altitude b. temperature [°C] and pressure [Pa] at an altitude of 40 km (top of Mars' troposphere)
