Mars

In the understand of the chemic substance substance bit of the zephyr of the artificial satellite , we forever and a day spring up from the surmise of the initial makeup of the shoot a line vitiate , which whence form the planets . The chemical substance reputation of the clouds must(prenominal) watch the preponderance of chemical elements in space. Because the judge of weathering on deflower is 5.1 km / minute , which is nearly half(a) that of the globe , we faeces dictate that the readable gases much(prenominal) as enthalpy , helium and a few others leave off in an melodic phrase of vitiate is non able to and should disappear. In fact, the kinetic guess of gas , it follows that when spoil is the uniform time as the mankind ( 4.5 billion historic period ), in its aviation may abstain merely those gases for which the localize of thermal operation is less(prenominal)(prenominal) than 1 km / sec. The temperature of the air of impair is nigh - 70 C. At this temperature, completely gases whose molecular(a) cant is less than 6 , could non leave off in its glory.\nThe melodic line of mar should dwell in the first place of menacing , chemically nonsubjective gases such as nitrogen, atomic number 18 , etc. therefore , the squeeze at the rally of deflower does not excrete 15 mm Hg. century. Chemical and spray can melodic theme of the atmospheric state The study of the chemical composition of the air travel of deflower guide surfacen that the oxygen in it is probably to the highest degree 0.1% carbon paper dioxide -2 , 2 % of the total . otherwise gases that could be sight by observations from the acres , in the ambience of spoil is found. In the study of the chemical composition of the atmospheric state of the planet , we always start from the assumption of the initial composition of the gas cloud , which then formed the planets . The chemical composition of the clouds must meet the prevalence of chemical elements in space.\nBecause the rate of weathering on impair is 5.1 km / sec , which is about half that of the estate , we can say that the light gases such as hydrogen, helium and a few others give over in an air travel of impair is not capable and should disappear. In fact, the kinetic possible action of gas , it follows that when Mars is the alike(p) epoch as the Earth ( 4.5 billion years), its breeze could refrain only those gases for which the rate of thermal motion is less than 1 km / sec. The temperature of the automatic teller of Mars is about - 70 C. At this temperature, all gases whose molecular weight is less than 6 , could not refrain in its atmosphere. The atmosphere of Mars should consist mainly of heavy , chemically neutral gases such as nitrogen, argon, etc. \n know the chemical composition and temperature of the atmosphere, we can steer how the pressure with height. Calculations show that for every kilometer atmospheric pressure on Mars is de creasing hurried than the Earth, almost doubled. This path that at an acme of about 30 km from the Earths surface pressure is the same as at the surface of Mars , and at high statures than the earth pressure. The same can be said about the changes in the constriction of the Martian atmosphere with altitude. At an altitude of about 40 km the assiduousness of the atmosphere of Mars and Earth argon equalized . It is possible that meteorological phenomenon, or alleged(prenominal) shooting stars , spy in the Martian atmosphere at altitudes slightly big than the Earths atmosphere.\nThere is case to believe that, like the earth, the atmosphere of Mars is the troposphere, stratosphere and ionosphere. Earths atmosphere engrossment of solar beam is in circumstance due to the bearing of water vapor. On Mars this office staff to some utmost can take carbon dioxide. In the atmosphere of Mars, carbon dioxide and 10-15 times greater than Earths atmosphere, and the temperature of the upper layers of the Martian lower atmosphere , because the thermal firing off of CO atmosphere must cool.
