Hey here's your answer
Explanation:
Scientists cooled a copper cube inside a cryostat, the first such container built that can keep substances so close to absolute zero. A chunk of copper became the coldest cubic meter (35.3 cubic feet) on Earth when researchers chilled it to 6 millikelvins, or six-thousandths of a degree above absolute zero (0 Kelvin).

A chunk of copper became the coldest cubic meter (35.3 cubic feet) on Earth when researchers chilled it to 6 millikelvins, or six-thousandths of a degree above absolute zero (0 Kelvin).This is the closest a substance of this mass and volume has ever come to absolute zero . Researchers put the 880-lb. (400 kilograms) copper cube inside a container called a cryostat that is specially designed to keep items extremely cold. This is the first cryostat built that is capable of keeping substances so close to absolute zero.
Hope these helped you ❣
