Problem 18.34

Calculate the mean free path of air molecules at 3.50 * 10-13 atm and 300 K. (This pressure is readily attainable in the laboratory; see Exercise 18.23.) As in Example 18.8, model the air molecules as spheres of radius 2.0 * 10-10 m.

Step-by-Step Solution:
Step 1 of 3

Week 8 Tuesday, October 11, 2016 10:52 AM  Superconducting magnets-: ○ Meissner effect- small permanent mag floats freely above N cooled ceramic superconductor bc has 0 resistance & expels any mag field from inside super creating mirror image of mag pole  Classify superconductors: ○ Conventional- explained by BCS theory  BCS- e- form cooper pairs to move around… phonon from vibration(causes pair formation), attract instead of repel here.. e- move easily w/out collisions ○ Unconventional- if not ○ Critical temp:  High T… Tc>77K □ Cool w liquid N  Low T… if need other techniques to be cooled ○ Resp to mag field  Type 1: single
