NEET Physics Ideal Gas Equation MCQ Question
If the pressure of an ideal gas is given by P = (1/3) n m v^2, where n is the number density, m is the molecular mass, and v is the speed, what happens to the pressure if the speed is doubled while keeping n and m constant?
The pressure becomes four times.
The pressure becomes twice.
The pressure remains the same.
The pressure becomes eight times.
Correct Answer
Detailed Explanation
According to the equation P = (1/3) n m v^2, if the speed v is doubled, the pressure P becomes four times since it depends on the square of the speed.
