o holy nightMolecules and Temperature Molecules in constant motion have kinetic energy.
The temperature determines
their average kinetic energy.
The higher the temperature,
the faster the molecules move.

veneerCRYOPUMPING BASICS: Capture Theory
Cryocondensation（冷凝）
Pumping gas by cooling them to point that
they conden, and freeze, on a surface. A
cryopump pumps water and “air” gas by cryocondensation; the gas forming a layer of frost on the condensing array.
