(a) Compute the root-mean-square speed of a nitrogen molecule at 99.6°C. The molar mass of nitrogen molecules (N2) is 28.0x10-3 kg/mol. At what temperatures will the root-mean-square speed be (b) 1/3 times that value and (c) 2 times that value?
(a) Compute the root-mean-square speed of a nitrogen molecule at 74.7°C. The molar mass of nitrogen molecules (N2) is 28.0×10-3 kg/mol. At what temperatures will the root-mean-square speed be (b) 1/3 times that value and (c) 2 times that value?
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.
EXAMPLE 6-14 Calculating a Root-Mean-Square Speed Which is the greater speed, that of a bullet fired from a high-powered M-16 rifle (2180 mi/h) or the root-mean-square speed of H2 molecules at 25 °C? Analyze This is a straightforward application of equation (6.19). We must use SI units: R = 8.3145JK mol- and M = 2.016 X 10-kg mol-1. Recall that 1 J = 1 kg m?s Solve Determine urms of H2 with equation (6.19). 3 x 8.3145 kg m’s 2...
