What is the relationship between the absolute temperature of a gas and the average kinetic energy of its molecules?.
- A.Directly proportional
- B.Inversely proportional
- C.No relationship
- D.Exponential relationship
Model answer
What a good answer should say
- Directly proportional
Explanation
Why this works
The average kinetic energy of gas molecules is directly proportional to the absolute temperature of the gas. As the temperature increases, the kinetic energy of the molecules also increases, leading to higher pressure if the volume is constant.
