NEET Physics Ideal Gas Equation MCQ Question
For an ideal gas, if the number of molecules increases by a factor of 3 while keeping the temperature constant, what happens to the pressure assuming volume remains unchanged?
The pressure triples.
The pressure remains the same.
The pressure doubles.
The pressure halves.
Correct Answer
Detailed Explanation
According to the ideal gas equation PV = nRT, if the number of molecules (n) increases by a factor of 3 and temperature (T) and volume (V) are constant, the pressure (P) must also triple.
