10.1 Characteristics of Gases

10.1 Characteristics of Gases. Air behaves physically as one gaseous material N 2 (78%), O 2 (21%) and Ar (0.9%) Only a few elements exist as gases under standard conditions H 2 , N 2 , O 2 , F 2 , and Cl 2 , the noble gases (He, Ne, Ar , Kr, Xe )

Vacuum Systems

Vacuum Systems. Why much of physics sucks. Why Vacuum?. Anything cryogenic (or just very cold) needs to get rid of the air eliminate thermal convection; avoid liquefying air Atomic physics experiments must get rid of confounding air particles eliminate collisions
