How does the average kinetic energy of gas molecules relate to temperature?.
- A.Higher temperature means lower average kinetic energy
- B.Higher temperature means higher average kinetic energy
- C.Temperature has no effect on kinetic energy
- D.Kinetic energy is independent of temperature
Model answer
What a good answer should say
- Higher temperature means higher average kinetic energy
Explanation
Why this works
The average kinetic energy of gas molecules is directly proportional to the absolute temperature. As temperature increases, the average kinetic energy of the molecules also increases, leading to higher pressure if the volume is constant.
