(a) Calculate Earth's escape speed-the minimum speed needed for an object near the surface to escape Earth's gravitational pull.
(b) Calculate the average speed of a hydrogen molecule (H2) at 0°C.
(c) Calculate the average speed of an oxygen molecule (O2) at 0°C.
(d) Use your answers from parts (a) through (c) along with what you know about the distribution of molecular speeds to explain why Earth's atmosphere contains plenty of oxygen but almost no hydrogen.
