Bose-einstein condensates

form when atoms move very quickly
are made of free electrons and ions
form at very cold temperatures
form when gas is heated

Bose-Einstein condensates form at very cold temperatures.

Explanation:

Bose-Einstein condensate is an aggregation state that matter can pass to at extremely low temperatures. Then the internal energy of the atoms decreases, and thus their amount of movement, which leads to an increase in uncertainty in their position. When the uncertainty exceeds the distance between bosons (atoms with integer spin), the atoms become indistinguishable particles. They end up in the same quantum mechanical ground state with the same wave function. The phase of the atoms becomes coherent and it can give rise to interference and diffraction patterns in a way comparable to laser light.
