NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 11
Assertion (A): The distribution of molecular speeds in a gas remains constant in a state of equilibrium.
Reason (R): Collisions between molecules change their speeds and directions even when bulk parameters like pressure, volume, and temperature are fixed.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true, but R is false.
D
A is false.
Correct Answer
Option A
Detailed Explanation
In the NCERT context, it is stated that in a state of equilibrium, the distribution of speeds is constant, and collisions change the speed and direction of molecules, supporting both the assertion and reason.
