At what temperature would the rms speed of helium atoms equal (a) the escape speed from Earth, 1.12 x 104 m/s and (b) the escape speed from the Moon, 2.37 x 103 m/s? Note: The mass of a helium atom is 6.64 x 10-27 kg.
Four tanks A, B, C, and D are filled with monatomic ideal gases. For each tank, the mass of an individual atom and the rms speed of the
atoms are expressed in terms of m and Vrms respectively (see the table). Suppose that m = 2.23 x 10-26 kg, and Vrms = 1050 m/s. Find the
temperature of the gas in each tank.
