NEET Physics (general) MCQ Question
Consider a hypothetical experimental setup where a gas is contained in a long, narrow, porous cylinder. The cylinder allows molecules to wander through individually, colliding with the walls of the pore. Which factor predominantly determines the rate at which different gas molecules leak out of the cylinder?

The molecular speed of the gas molecules.
The atomic structure of the gas molecules.
The temperature outside the cylinder.
The density of the gas inside the cylinder.
Correct Answer
Detailed Explanation
The rate at which gas molecules leak out of a porous cylinder is predominantly determined by their molecular speed, as faster molecules will leak out more easily. This is related to the Maxwell Distribution Function, which describes the speed distribution of molecules.
