The density of air molecules at room temperature (295 K) and atmospheric pressure is about 2.7 × 1025 molecules/m3. Their average mass is 4.8 × 10-26 kg. Use this and equation to answer the following.
(a) What is the flux of particles striking a wall of your room (in particles per square meter per second)?
(b) If a micrometeorite punctured a hole 0.2 mm in diameter in the wall of a spaceship, at what rate would molecules leave if the air were held at atmospheric pressure and room temperature?
