At very low temperature, the de Broglie wavelengths of the atoms in a gas can become larger than the distance between atoms, which leads to new states of matter. In an early study, a gas of 23Na was cooled to 200 nK. What is the de Broglie wavelength of the sodium atoms at this temperature? To get a sense of scale, at everyday temperatures and pressures, the distance between air molecules is about 3 nm. How does the de Broglie wavelength compare to this distance? (The gas in the study was much more diffuse than this, but the atoms were close enough for some overlap.)
The root mean square speed of the hydrogen molecules at temperature t °C is given
by
3x8.31 x (t+273) m
2 x 10-3
Calculate the de Broglie wavelength (in nanometers) of the hydrogen molecules at
temperature 24 °C. The mass of the hydrogen molecule is 2 x 1.66 x 10-27 kg. Use two
decimals in your answer.
