Question

The speed of the particles of a substance is 0 at which of the following temperatures?

  1. 0 K
  2. 0oC
  3. 0oF
  4. All of the above

hintHint:

Speed ceases at absolute zero

The correct answer is: 0 K


    0 K is the temperature at which all particle motion has stopped, not that particle motion stops because it has reached absolute zero (0K).
