Solution
Correct Answer:
Remains same
The Kinetic Theory of Gases explicitly states that the average translational kinetic energy of a molecule is solely a function of temperature: Kˉ=23kBT.
- If the temperature is constant, Kˉ remains the same.
- A pressure increase at constant T must be caused by an increase in number density (N/V, i.e., compression), not by the individual molecules hitting the walls harder on average.
This hard difficulty physics question is from the chapter kinetic theory of gases, covering the topic of pressure increase hard. It appeared in the 2025 exam.
