Question
The speed of the particles of a substance is 0 at which of the following temperatures?
- 0 K
- 0oC
- 0oF
- All of the above
Hint:
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).
