Question 7: Check the box entitled allow escape from chamber in the chamber properties panel. You should still have an evenly balanced mixture of hydrogen, ammonia, and carbon dioxide. Run each of the simulations specified in the table below for the mixture. Click reset proportions to restore the original gas levels. Write a description of the results similar to the example completed for you.

H2 is very quickly lost since it only has a mass of 2u and its most probable velocity is greater than the escape velocity, NH3 is slowly lost since it is a medium mass gas (18u) and a significant fraction of its velocity distribution is greater than 1500 m/s, CO2 is unaffected since its most probable velocity is far less than the escape velocity.

Explanation / Answer
at 500K most probable velocity
H=2497 m/s, NH3= 832.38m/s CO2=532.39m/s
at 100K, most probable velocity
H=1116.76m/s NH3=372.25m/s CO2=238m/s
2)in this case hydrogen molecules will escape, NH3 is close to the escape velocity so, it can lost slowly and will not affect carbon dioxide due to its low probable velocity.
3) in this case all molecules are capable of escape from the gravity since the most probable velocity is higher for all molecules than the escape velocity.
4) in this condition no molecule will escape, including Hydrogen, they will not have sufficient energy to escape, the most probable velocity at this temperature is less thn the escape velocity.
5) Hydrogen molcules will escape in this conditon, and NH3 and CO2 will remains there.
6)
in this case hydrogen molecules will escape immediately and the probable velocity of NH3 is less but some molecules can escape slowly, but no molecules of co2 can escape since their most probable velocity is less than the escape velocity.
