NEET Physics Ideal Gas Equation Assertion Reason Question
Assertion (A): In an ideal gas, the average speed of molecules remains constant over time. | Reason (R): In dynamic equilibrium, the average properties of a gas are constant despite molecular collisions.
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 but R is true.
Correct Answer
Detailed Explanation
While the Reason is true as dynamic equilibrium maintains constant average properties, the Assertion is false because individual molecular speeds vary due to collisions.
