    Thermodynamics involving escape velocity and Boltzmann factor

    That tells you the probability doesn't it? So if T is low the probability is also low?

    Thermodynamics involving escape velocity and Boltzmann factor

    That tells you the probability doesn't it? So if E is higher then the probability is lower, and vice versa?

    Thermodynamics involving escape velocity and Boltzmann factor

    At 293K, helium atoms have a root mean square speed of about 1.35 km/s, whereas escape velocity at the Earth's surface is about 11km/s. Explain why is it nevertheless possible for helium atoms to escape from the Earth into space. Is it because near the top of the atmosphere the temperature...
