NEET Physics (general) Assertion Reason Question
Assertion (A): The distribution of molecular speeds in a gas is constant in equilibrium. | Reason (R): Collisions among molecules change their speed and direction.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false.
Correct Answer
Detailed Explanation
In equilibrium, the distribution of speeds is constant because, although collisions change individual speeds and directions, the overall statistical distribution remains unchanged.
