Exam-style question
Try this first
At absolute zero, what is the expected average kinetic energy of gas molecules?.
- A.Maximum kinetic energy.
- B.Zero kinetic energy.
- C.Infinite kinetic energy.
- D.Negative kinetic energy.
Model answer
What a good answer should say
- Zero kinetic energy.
Explanation
Why this works
Absolute zero is the theoretical temperature at which molecular motion stops, resulting in zero average kinetic energy for the gas molecules.
