Question

choose the correct answer. why havent scientists ever been able to get a substance to reach absolute zero? because its too expensive because the particles in all known substances can never completely stop moving

Explanation:

Absolute zero is the theoretical temperature at which all molecular motion stops. In reality, the particles in all known substances can never completely stop moving due to the laws of quantum mechanics and thermodynamics. Cost is not the fundamental reason.

Answer:

because the particles in ALL known substances can never completely stop moving
