NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 11
Assertion (A): In a given mass of gas, the velocities of all molecules are not the same.
Reason (R): Collisions change the direction and the speed of molecules, maintaining a constant speed distribution in equilibrium.
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, but R is true.
Correct Answer
Option A
Detailed Explanation
The NCERT context states that in a mass of gas, molecular velocities vary due to collisions, but the speed distribution remains constant in equilibrium, supporting both A and R.
