How many substances are solids at 0 degrees kelvin?

Answer 1

Zero on the kelvin scale is the lower limit of the temperature scale, and thus cannot be reached. A chemical at zero degrees Kelvin has no internal energy and thus does not exist.

0 Kelvin is also known as absolute zero.

Laboratory experiments routinely produce temperatures close to absolute zero, but it is impossible to be at 0 K.

The average temperature of the universe is 2.73 Kelvin.

Answer 2

No one knows what happens to a substance at absolute zero because scientists have never succeeded in getting anything that cold. They have gotten to within less than a degree of it however. Theoretically the atoms in the matter would stop vibrating. No one knows what the result of that would be for certain.
