Question

6. (a) Find the de Broglie wavelength of a nitrogen molecule in air at room temperature
(293K). (b) The density of air at room temperature and atmospheric pressure is 1.292
kg/m3. Find the average distance between air molecules at this temperature and
compare with the de Broglie wavelength. What do you conclude about the importance
of quantum effects in air at room temperature? (c) Estimate the temperature at which
quantum effects might become important.
