A jar is filled with monatomic helium gas at a temperature of 25 C. The pressure inside

Question:

A jar is filled with monatomic helium gas at a temperature of 25 °C. The pressure inside the jar is one atmosphere; that is, 101 kPa.

(a) Find the average de Broglie wavelength of the helium atoms.

(b) Calculate the average separation between helium atoms in the jar. (The fact that the spacing between atoms is much greater than the de Broglie wavelength means quantum effects are negligible, and the atoms can be treated as particles.)
