A Quantum Gas

by Slobodan Danko Bosanac
A Quantum Gas
for 22 and upwards,
Lectures | 22 and upwards | 9 years ago | 863 views
Rating:

The quantum gas is an extreme state of an ensemble of atoms when their de Broglie wave length is of the same length as the size of the container. The ways of achieving this state are described and also how its temperature is defined.
