A pressure as low as P = 7 x 1011 Pa has been obtained. Suppose a chamber
Question:
A pressure as low as P = 7 x 10–11 Pa has been obtained. Suppose a chamber contains helium at this pressure and at room temperature (300 K). Estimate the mean free path l and the collision time t for helium in the chamber. Take the diameter of a helium molecule to be 10–10 m.
