Question

14. Using internet searchable data and an assumed exosphere temperature of 200 °K, assess whether you should expect the following gasses in the atmosphere of Titan. Next to each, write either "escapes" or "bound". Assume no replenishment. Remember, a gas can be assumed to escape if the average velocity is greater than 1/6thof the escape velocity. Useful equations: (3 points) 3 2GMT esc Where: k 0.008 amu km/s2 "m" is in terms of the mass of hydrogen (mH), which is 1 atomic mass unit (amu). If you search Google for "mass of oxygen", for instance, it will return "15.999 u", which you can round to 16 u (u is the same as amu) and you can plugin to "m" as 16 G is the gravitational constant (6.67 x 1020 km' kg s2) Mr is the mass (in kg) and R is the radius of Tian (in km). You can Google those i. Hydrogen 11. oxygen iii. Molecular Nitrogen (N2). Twice the mass of a nitrogen atom.
