DCGN209-Spring’10: Homework#4 p. 1 of 2 I. to hand in) . A. (3 pts) A gas is most likely to behave as an ideal gas at: low T low T high T high T low P high P low P high P B. (2 pts each) Consider He (M = 4.0026 g mole -1 ) at 21.2 0 C. 1. The average, molar kinetic energy for He at this temperature (in Joules) is: 36.23 264.40 3671.1 2. The root-mean squared speed for He at this temperature (in m sec -1 ) is: 42.83 134.55 1354.4 C. (2 pts each) Compare Ne (M = 20.18 g mole -1 ) to He from part C . 1. At what temperature ( 0 C) will Ne have the same molar kinetic energy as He at 21.2 0 C: 21.20 387.78 1210.9 2. At what temperature ( 0 C) will Ne have the same root-mean-squared speed as He at 21.2 0 C: 21.20 0 C 387.78 0 C 1210.9 0 C 1484.0 0 C
