WebAug 23, 2015 · 7. @jheindel Yes, escape velocity on Earth is 11.2 km/s (Mars: 5.0 km/s; Moon: 2.4 km/s). The average speed of a hydrogen atom (M = 1 g/mol) at T = 1000 K is about 5 km/s. (Note that the temperature in Earth’s exosphere can be well above 1000 K.) Particles from the high-speed tail of the Maxwell distribution may actually reach escape … WebEventually, there will be an equilibrium of the upward buoyant force and the downward gravitational force, where the Helium molecule will remain if left alone. However, there are forces at work that can allow Helium to escape the atmosphere. The main one seems to be heat from the Sun. Obviously, the Sun heats the atmosphere. how is phys doing on the stock market today

WebThe smaller the object, the lower the gravity, so the escape velocity is lower and it is harder to retain an atmosphere (Moon and Mercury). Finally, you can lose atmosphere to the surface. The atmosphere can condense onto the surface (rain and snow). On Earth, much of the carbon dioxide that is normally generated is dissolved into the oceans. 2. WebApr 12, 2024 · 5. And while there's some (very slow) escape of gas, that depends on the molecular weight of the gas. So while hydrogen & helium escape relatively easy, the principle GHG, carbon dioxide, is heavier than either atmospheric oxygen & nitrogen. So if anything, escape into space would result in a HIGHER GHG concentration. – jamesqf.
