A helium-4 atom has a mass of 6.65 x 10-27 kg. (a) What temperature (in K) would a gas composed entirely of helium-4 atoms have to be at in order for the rms speed of the atoms to equal the escape speed from Earth, 1.12 x 104 m/s? K (b) What temperature (in K) would a gas composed entirely of helium-4 atoms have to be at in order for the rms speed of the atoms to equal the escape speed from the Moon, 2.37 x 10³ m/s? K
