Question

At what temperature will the rms speed of oxygen molecules become just sufficient for escaping from the Earth’s atmosphere? (Mass of oxygen molecule (m) = 2.76 × 10^-26 kg Boltzmann’s constant (k_B) = 1.38 × 10^-23 JK^-1 )

Answer 1

v_escape = 11200 ms^-1

say at temperature T it attains v_escape
