NEET Physics Ideal Gas Equation MCQ Question
A container of volume V contains a gas at pressure P and temperature T. If the number of molecules in the container doubles, how does the pressure change, assuming the volume and temperature remain constant?
Pressure remains the same.
Pressure doubles.
Pressure halves.
Pressure quadruples.
Correct Answer
Detailed Explanation
According to the ideal gas equation PV = k_B NT, if the number of molecules (N) doubles at constant volume (V) and temperature (T), the pressure (P) must also double.
