Bose Einstein Condensate

BEC can only be formed at temperatures as low as a few billionths (0.000,000,001) of a degree above Absolute Zero. Atoms will be at different energy levels at normal temperatures, but once the tempera ...

the temperature and pressure measurements on a graph.Pressure decreases when temperature decreases. Absolute Zero has been determined to be at -273.15°C. Therefore one could determine that at -273 ... t -273°C there would be no pressure because no collisions of the gas molecules could occur. The Absolute Zero Temperature Scale is also known as the Kelvin Temperature Scale. Since we know that Ab ...
