NEET Physics Ideal Gas Equation Assertion Reason Question
Assertion (A): An ideal gas follows the equation PV = μRT at all pressures and temperatures. | Reason (R): The number of molecules per unit volume is the same for all gases at a fixed temperature and pressure.
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 both the assertion and reason are true, the reason does not explain why an ideal gas follows PV = μRT. The ideal gas equation is derived from the kinetic theory, not directly from Avogadro's hypothesis.
