Two vessels are labeled A and B. Bessel A contains NH3 gas at 68 C, and vessel B contains Ne gas at the same temperature. If the average kinetic energy of NH3 is 7.1 x 10^-21 J / molecule at 70 C, calculate the root-mean-square speed of Ne atoms in m/s.My main problem is in converting the average kinetic energy of NH3 at 70 C to average kinetic energy of NH3 at 68 C?
