NEET Physics Mean Free Path MCQ Question
Which of the following statements about the mean free path in gases is correct?
The mean free path is inversely proportional to the density of the gas.
Mean free path increases with higher molecular mass.
Molecules with higher speeds will have shorter mean free paths.
The mean free path is unaffected by the temperature of the gas.
Correct Answer
Detailed Explanation
The mean free path is influenced by the density of the gas; as density increases, the frequency of collisions increases, leading to a shorter mean free path. This aligns with the understanding of molecular collisions in gases.
