NEET Physics (general) MCQ Question
Which of the following statements regarding molecular speed distributions and properties of gases is correct?
In a gas at equilibrium, the speed distribution of molecules remains constant over time.
All gas molecules have the same speed when the pressure and temperature are constant.
The distribution of molecular speeds is influenced by the mass of the gas molecules.
Higher molecular speeds result in lower average kinetic energy for the gas.
Correct Answer
Detailed Explanation
At equilibrium, while individual molecule speeds may vary, the distribution of speeds remains constant, as stated in the context regarding the Maxwell Distribution Function.
