Try this first
In an ideal gas, if the temperature increases, what happens to the average kinetic energy of the gas molecules?.
- A.It decreases
- B.It remains the same
- C.It increases
- D.It becomes zero
Model answer
What a good answer should say
- It increases
Explanation
Why this works
The average kinetic energy of gas molecules is directly proportional to the absolute temperature. As temperature increases, the kinetic energy of the molecules also increases.
