what chemical can move at absolute zero?

Answer 1

helium becomes superfluid at absolute zero. absolute zero is the temp at which all molecules cease motion.

Answer 2

Absolute zero is the theoretical lowest temperature an object can achieve. Temperature is the measure of the average kinetic energy of the particles of a system. Kinetic energy relates the mass and speed of a particle to its energy. Therefore, the slower the particles are moving, the lower the temperature.
At absolute zero, the particles come to a complete stop.

Answer 3

Superfluid He does not exsist at 0 K, but close. Niether does all motion stop, electrons still move, but all transitional and vibrational motion (should) be non-exsitant.

Since temperature is a means of measuring vibrational, rotational, and transistional motion of a molecule, all compounds can, theorheticly, exsist at 0K. However 0 K is a theory, it can not be truely ever met, just like an ideal gas does not exsist.

Answer 4

Helium... it becomes a "superfluid."

And, counterintuitive as it may seem... there are negative temperatures too. They are not colder than absolute zero, but are weighted toward filling high-energy states more densely than the low-energy states (an inversion). It is an interesting quirk of statistical mechanics.

Answer 5

None. At absolute 0, ALL motion stops. Even electrons. Matter as we know it could not exist. That is why noone has ever obtained absolute 0 & never will.

Answer 6

Helium. At absolute zero, it becomes a superfluid that can resist gravity and a group of particles act as one.

Answer 7

None...
Absolute zero is defined as the point of cessation of all molecular movement...
