At what temperatures does the rms speed of (a) H2(molecular hydrogen) and (b) O2 (molecular oxygen) equalthe escape speed from Earth (escape speed=11.2 km/s) ? At whattemperature does the rms speed of (c) H2 and (d)O2 equal the escape speed from the Moon (where thegravitational acceleration at the surface has magnitude0.16g)? Considering the answers to parts (a) and (b), shouldthere be much (e) hydrogen and (f) oxygen high in Earth's upperatmosphere, where the temperature is about 1000 K?The answers are:(a) 1.0 Γ 104 K;(b) 1.6 Γ 105 K;(c) 4.4 Γ 102 K;(d) 7.0 Γ 103 K;(e) no;(f) yes
