At what temperature is the root-mean-square speed of nitrogen molecules equal to the root-mean-square speed of hydrogen molecules at 46 oC? (Hint: The molar mass of hydrogen atoms is 1.008 g/mol and of nitrogen atoms is 14.007 g/mol. The molar mass of H2 is twice the molar mass of hydrogen atoms, and similarly for N2.) The answer is in degree C.
Which of the following statements is true for real gases? Choose all that apply Attractive forces between molecules cause a decrease in pressure compared to the ideal gas. Attractive forces between molecules cause an increase in pressure compared to the ideal gas. As molecules increase in size, deviations from ideal behavior become more apparent at relatively low pressures. As attractive forces between molecules increase, deviations from ideal behavior become more apparent at relatively low temperatures. Compute the root-mean-square speed of...
