Question: 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? The response must be typed, single spaced, must be in times new roman font (size 12) and must follow the APA format.
