Modern vacuum pumps permit the pressures down to 4.1 × 10⁻¹¹ atm to be reached at room temperature (27°C). Assuming that the gas exhausted is nitrogen, find the mean distance between the gas molecules remained at this pressure.
Options:
Answer:
B
Solution:
N* = p/(kT) = ((4.1×10⁻¹¹)/)(1.013×10⁵)(1.38×10⁻²³)(300) ≈ 1.0×10¹⁵·m⁻³. Mean separation d ≈ (N*)-1/3 = (1.0×10¹⁵)-1/3 m = 10⁻⁵ m = 10⁻³ cm. Confirms Ans (b) 1 × 10⁻³ cm.
