The kinetic energy of gas molecule is zero at_____________________?
Correct answer: D. -273°C
- A. 0°C
- B. 273°C
- C. 100°C
- D. -273°C
Explanation
The average translational kinetic energy of gas molecules is proportional to absolute temperature, so it approaches zero at 0 K. This corresponds approximately to −273°C, not to 0°C.
